Electrochemical H 2 O 2 synthesis via the two-electron oxygen reduction reaction (2e – ORR) offers a green alternative to the energy-intensive anthraquinone process, but its practical viability is hindered by the sluggish and low-value oxygen evolution reaction (OER) at the anode. Here, we present an energy-saving paired electrolysis strategy that replaces anodic OER with methanol oxidation reaction (MOR) using a ternary Mn-doped NiCo layered double hydroxide (Ni 0.50 Co 0.30 Mn 0.20 LDH) catalyst in situ grown on nickel foam (NF) by a one-step hydrothermal method. The optimized catalyst achieves a low MOR potential of 1.32 V RHE at 10 mA cm –2 and a formate Faradaic efficiency of 92.9%, outperforming its undoped counterpart (Ni 0.61 Co 0.39 LDH, 1.37 V RHE and 83.3%). In-situ Raman spectroscopy and density functional theory calculations reveal that Mn doping lowers the energy barrier for the Ni 2+ /Ni 3+ redox transition, facilitating the generation of catalytically active Ni 3+ species. When coupled with graphitized hydroxyl-functionalized multi-walled carbon nanotubes coated on carbon paper (CNTs@CP) as the 2e – ORR cathode in a two-electrode electrolyzer, at the operation condition of 50 mA cm –2 , the 2e – ORR||MOR system delivers a cell voltage reduction of 254 mV, enabling a 10.3% decrease in energy consumption for H 2 O 2 production, compared with the conventional 2e – ORR||OER system. Moreover, the simultaneous generation of value-added formate at the anode yields a 97.9% increase in net economic benefit. This work establishes a generalizable paired electrolysis paradigm for the decentralized, energy-efficient, and economically viable co-production of H 2 O 2 and high-value chemicals.

Pt-based catalysts exhibit a strong negative correlation between oxidation efficiency and OVOC carbon chain length. • Mn-based catalysts maintain stable oxidation performance across OVOCs with different functional groups. • The catalytic activity of Mn-based catalysts is governed by manganese oxidation states, while that of Pt-based catalysts relies on metal-support interactions that modulate Pt dispersion and oxidation states. • The reaction pathways for OVOCs oxidation are governed by catalyst type and functional group. The catalytic oxidation of oxygenated volatile organic compounds (OVOCs) is highly governed by both their functional groups and catalyst types. However, systematic investigations into the structure-activity and selectivity relationships across different OVOCs and catalyst systems remain limited. In this work, three Pt-based catalysts (Pt/TiO 2 , Pt/Al 2 O 3 , Pt/SiO 2 ) and three Mn-based oxides (MnO 2 , Mn 2 O 3 , Mn 3 O 4 ) were systematically evaluated for the catalytic elimination of four typical OVOCs, namely ethanol, methyl formate, acetone and ethyl acetate. The performance of Pt-based catalysts showed a strong dependence on OVOCs carbon chain length, whereas Mn-based catalysts exhibited broader applicability for OVOCs degradation. The reaction pathway and energy barrier are dictated jointly by the functional groups of the OVOCs and the surface/redox properties of the catalysts. These findings advance the understanding of structure-activity relationships in OVOCs catalytic oxidation and provide crucial guidance for the rational design of high-performance catalysts for targeted VOCs removal.

MnBGs+ had multiple functions for hemostasis and wound healing. • MnBGs+ can be electrostatically adsorbed on the surface of sponge. • HH-MnBGs+ directional sponge can significantly shorten the water absorption time. • HH-MnBGs+ sponges can synergistically stop bleeding through various methods. • HH-MnBGs+ sponges can clear ROS, inhibit inflammation and promote wound healing. The control of major bleeding in accidents or clinical settings is a critical area that needs to be developed in the current medical field. Cryogel sponges have excellent hemostasis and wound healing potential due to its high porosity and water absorption. Here, a composite sponge (HH-MnBGs+) of natural polymer and positively charged Mn-doped bioactive glass nanofibers (MnBGs+) was prepared. The main body of sponge is composed of hyaluronic acid (HA) and hydroxypropyl chitosan (HPCS). The directional channels are constructed through directional freezing method and they can absorb water more quickly through capillary action. MnBGs+ were prepared by electrospinning methods and quaternized with silane coupling agents and adsorbed onto the surface of the channels through electrostatic interactions to facilitate rapid contact between them and blood or tissue. These multifunctional nanofibers adsorbed in the channel can respond to the external environment in a timely manner and achieve multifunctionality in antibacterial, anti-inflammatory, hemostatic, and healing promotion. When blood flowed into the channel, red blood cells (RBCs) and platelets were adsorbed on the surface of channel and form the artificial thrombus. Moreover, MnBGs+ can effectively alleviate inflammation and promote wound healing by removing reactive oxygen species (ROS) and accelerating angiogenesis. Thus, HH-MnBGs+ sponge has a great potential for application in non-compression hemostasis and wound healing. Download: Download high-res image (165KB) Download: Download full-size image

Halide perovskites are promising for applications in light-emitting diodes, multilevel anti-counterfeiting, and radiation detection due to their excellent luminescence properties. Mn 2+ doping can further tailor the optical properties of perovskites, yet its microscopic mechanism remains insufficiently understood. Here, we report a gradient orbital coupling-enhanced red emission with a nearly tenfold increase in photoluminescence quantum yield by doping 0.12% Mn 2 + into 1D NH 4 CdCl 3 perovskite, constructing asymmetric Cd-Cl-Mn functional units. First-principles calculations indicate that orbital hybridization among Cd(5s, 4d), Cl(3p), and Mn(3d) orbitals in these asymmetric Cd-Cl-Mn units creates a stepped carrier-transport pathway via the formation of coupled gradient orbitals. Transition dipole moment analysis and partial charge mapping reveal that electrons transiently occupy the conduction-band-coupled Mn 3d orbitals before relaxing to the conduction band minimum, while most of the holes are localized at Cd sites. This carrier redistribution enhances radiative recombination, thereby optimizing emission efficiency. The as-prepared semitransparent scintillator films incorporating NH 4 CdCl 3 : Mn deliver strong 630 nm emission under x-ray excitation for high-resolution imaging. Our findings demonstrate that gradient orbital coupling serves as an effective strategy for enhancing luminescence, paving the way for high-efficiency perovskite-based optoelectronic materials and devices.

Liver cancer remains a major global public health threat, with high mortality. Lenvatinib is a tyrosine kinase inhibitor that has been used for the treatment of advanced liver cancer. However, its therapeutic efficacy is often limited by severe adverse effects and drug resistance. To overcome these challenge, we developed a biomimetic versatile nanoplatform based on Mn-doped polydopamine (PML@CM). Owing to their homologous tumor-targeting ability and pH-responsive drug release properties, PML@CM nanoparticles effectively improved the biocompatibility of lenvatinib and enhanced its tumor accumulation. Upon exposure to the tumor microenvironment, the released Mn2+ not only triggered chemodynamic therapy through Fenton-like reactions but also enabled magnetic resonance imaging (MRI). In addition, PML@CM nanoparticles exhibited an efficient photothermal conversion performance for tumor photothermal therapy. In conclusion, this nanoplatform provides a promising therapeutic strategy for MRI-enabled synergistic therapy against liver cancer.

Mn-doped BaTiO 3 with modulated band structure and carrier dynamics. • Synergistic SDT/CDT achieved via Mn-doping and piezoelectric catalysis. • US accelerates Fenton-like reactions for improved CDT efficacy. Piezoelectric-based sonodynamic therapy (SDT) under ultrasound (US) excitation has garnered increasing attention in cancer treatment. Barium titanate (BTO) is a typical piezoelectric material with the advantage of good biocompatibility. However, the hypoxic microenvironment of tumors limits the reactive oxygen species (ROS) production of piezoelectric materials. In this study, BTO/Mn/PDA/Trop-2 was prepared via hydrothermal and self-layered assembly methods for the treatment of bladder cancer. The BTO generates reactive oxygen species (ROS) through the piezoelectric effect under US irradiation. The bandgap of BTO was reduced by Mn doping, which accelerated electron movement and enhanced the piezoelectric effect of BTO to strengthen SDT. Additionally, Mn exhibited Fenton reaction activity, converting endogenous hydrogen peroxide into hydroxyl radicals, and US enhanced CDT by promoting Mn release. The enhanced SDT and CDT of BTO/Mn/PDA/Trop-2 demonstrate inhibitory effects on bladder cancer both in vitro and in vivo . This work achieved bladder cancer treatment by simultaneously enhancing the SDT and CDT of piezoelectric materials. Download: Download high-res image (103KB) Download: Download full-size image

As a neurotransmitter that is present in minute amounts but indispensable to the human body, adrenaline (AD) plays a significant role in many physiological activities, so the precise detection of AD is essential for both clinical diagnosis and life science research. Thus, in this study, a cobalt‑manganese bimetallic doped metal-organic framework (Co/Mn@ZIF) was synthesized in a simple and low-cost manner. Additionally, when Co/Mn@ZIF was employed in a dual-readout platform that coupled UV–visible spectrophotometry with chemiluminescence (CL), the system delivered both excellent accuracy and good selectivity for the determination of AD. The UV–visible spectrophotometric method presented a linear concentration range of 0–100 μM and a limit of detection (LOD) of 0.879 μM, meanwhile, the linear range of the CL detection was 0.1–40 μM, with a LOD of 0.872 μM. The proposed dual-mode method furnishes a straightforward and economical means for the sensitive detection of AD, with promising applicability in clinical assays, environmental monitoring, and other potential scenarios.

Spinel lithium manganate (LiMn 2 O 4 ) is a promising cathode material for lithium-ion batteries (LIBs) due to its non-toxicity, cost-effectiveness, and recyclability. However, its development is hindered by rapid capacity degradation and structural collapse caused by Jahn-Teller distortion and Mn-ions dissolution. In this work, a dual-functional LaNiO 3 coating on LiMn 2 O 4 particles was introduced to prevent direct contact with the F-containing electrolyte, meanwhile, apply compressive stress on the surface of LiMn 2 O 4 , suppressing surface MnO 6 octahedra distortion and preserving cubic symmetry during deep charge-discharge cycles. The strong La–O bonds can strengthen interface Mn–O bonds and increase the activation energy for Mn-ions disproportionation and acid erosion, thus reducing Mn-ions dissolution. Additionally, LaNiO 3 can serve as a conductive synapse to improve conductivity of LiMn 2 O 4 and optimize the Li + migration pathway at the electrode-electrolyte interface, reducing the migration potential barrier of Li + . Electrochemical tests show that the 1 wt% LaNiO 3 -coated LiMn 2 O 4 cathode achieves an initial discharge capacity of 130.37 mAh/g with a capacity retention of 92.27% after 600 cycles. This performance is significantly superior to that of the unmodified LiMn 2 O 4 , which only exhibits an initial capacity of 115.63 mAh/g and a retention of 79.55%. This work offers an effective strategy to enhance LiMn 2 O 4 stability and capacity and provides a theoretical basis for using perovskite materials in surface modification.

Developing highly efficient and stable catalysts for hydroxylamine nitrate (HAN) decomposition is challenged by their tendency to sinter and suffer a sharp loss in specific surface area at high temperatures. Herein, a series of manganese-substituted lanthanum hexaaluminate (LMxA, x = 0, 0.5, 1, 2, 3) nanomaterials were prepared by coprecipitation-decarbonization templating method, and the effect of manganese doping on structure and the catalytic activity for HAN decomposition were systematically investigated. XRD and BET characterization revealed that the manganese substitution significantly regulated the structural properties of hexaaluminate nanomaterials, among which pure-phase LaMnAl11O19 (denoted as LM1A) exhibited excellent high-temperature structural stability. After calcination at 1400 °C for 12 h, the grain size increased only slightly from 24.1 to 28.7 nm, and the specific surface area retained at 15.8 m2·g–1, indicating outstanding resistance to nanoparticle sintering. Notably, LM1A served dual roles as both a catalytic support and an active component, exhibiting a stable catalytic efficiency for HAN decomposition, which could significantly reduce the initial decomposition temperature from 162.0 °C (thermal decomposition) to 120.4 °C. Manganese doping lowers the reaction energy barrier, as confirmed by critical kinetic parameters. Rational nanoscale regulation of manganese doping in hexaaluminate significantly enhances the high-temperature stability, providing an important reference for the development of highly efficient and long-life HAN decomposition catalysts.

The rational design and fabrication of high-efficiency catalysts for Fenton-like reactions have become a central research direction. As a recently emerging catalyst of great interest, the catalytic performance of bimetal-doped g-C 3 N 4 (graphitic carbon nitride) is still limited by the electron transfer. In this study, Fe and Mn co-doped g-C 3 N 4 (designated as Fe/Mn-CCN) was prepared via a co-sintering method, which an internal electric field was formed via a homojunction generation from the introduction of cyano groups (-C N) in Fe/Mn-CCN, enhancing electron transfer and catalytic activity for the degradation of tetracycline (TC) through the Fenton-like reaction. Simultaneously, it modulated the electronic density of metal active sites to enhance the adsorption capacity for TC and PMS. The rate constant of the reaction is 4.34 times higher than that of the pristine bimetallic catalyst (Fe/Mn-CN). The turnover number (TON) of Fe/Mn-CCN reaches as high as 32 × 10 −4 (g/L min) −1 , outperforming most reported graphitic carbon nitride (g-C 3 N 4 )-based catalytic systems with a significant enhancement in catalytic efficiency. Furthermore, the degradation efficiency retains 90% after continuous cyclic reactions for 12 h, demonstrating its excellent structural stability. This study provides a new perspective for the development of environmentally friendly materials used in pollutant degradation.

Piezocatalysis holds great potential for advanced oxidation processes (AOPs), yet the practical application of conventional powder catalysts is severely hindered by their poor recoverability and reusability. To overcome the limitation, a polyvinylidene fluoride (PVDF)-based piezocatalytic nanofibrous membrane embedded with manganese-doped bismuth sodium titanate (BNMT) was fabricated via electrospinning, with polyethylene glycol (PEG) incorporated as a hydrophilicity enhancer under sonication. Under ultrasound-assisted peroxymonosulfate (PMS) activation in a continuous-flow system, the optimized membrane (0.3B-PEG-PVDF) achieved 90.7 % degradation of tetracycline hydrochloride (TC, 10 mg/L) within 60 min. Quenching experiments and electron paramagnetic resonance spectroscopy revealed a unique mixed radical/non-radical pathway, with singlet oxygen ( 1 O 2 ) and hydroxyl radical (•OH) as the dominant reactive species. The piezocatalytic membrane maintained over 77 % TC removal after eight consecutive cycles, with negligible metal leaching and excellent anti-interference performance in real water matrices. This work provides a facile strategy for constructing efficient, recyclable piezocatalytic membranes and advances the practical application in continuous-flow wastewater treatment.

The Fe–Cu–Mn based layered oxides have gained considerable attention as particularly promising cathode materials for sodium-ion batteries (SIBs) due to their low cost, earth abundance, and favorable electrochemical properties. However, current research often treats this system as a unified matrix, which obscures the specific contributions of the individual Fe, Cu, and Mn components in determining structural stability and electrochemical performance. Herein, we systematically investigate the ternary Fe–Cu–Mn system without the addition of extraneous elements. By precisely tuning the stoichiometric ratios of Fe, Cu, and Mn within a Mn-rich layered framework, a direct correlation is established between composition, structure, and electrochemical behavior. It reveals that optimizing the Fe/Cu/Mn ratio effectively suppresses undesirable phase transitions, enhances structural stability, and results in superior electrochemical performance. The Na 0.70 Fe 0.15 Cu 0.15 Mn 0.70 O 2 (NFCM-0.70) cathode delivers a high initial energy density of 293.87 Wh kg −1 (based on the mass of the cathode) and presents the excellent capacity retention of 82.9% after 100 cycles at 0.2C. This work underscores the importance of rationally controlling intrinsic component ratios as a strategy for developing low-cost, high-performance layered oxide cathodes for SIBs.
