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.

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.

Thiram, a widely used dithiocarbamate pesticide, can threaten ecological systems and human health through residual contamination. Here, manganese and nitrogen co-doped carbon dots (Mn, N-CDs) were harnessed as a photo-driven oxidase-like nanozyme to build a visual colorimetric assay for thiram. Under light irradiation, Mn, N-CDs can generate singlet oxygen ( 1 O 2 ) and superoxide (O 2 − ·) and maintain good photozyme activity over a broad pH range. The Mn, N-CDs/3,3′,5,5′-tetramethylbenzidine (TMB) mixture produces a blue oxidized product under illumination; after introducing thiram, the oxidation of TMB is suppressed because thiram consumes 1 O 2 and O 2 − ·, thereby producing a thiram concentration-dependent color-fading signal. Notably, extending the irradiation time enhances the analytical sensitivity by allowing the chromogenic reaction to approach a more stable readout. The proposed method can be coupled with smartphone-based RGB quantification to enable portable digital readout under natural light. In addition, satisfactory recoveries and repeatability were obtained in diverse real water samples. The proposed approach thus offers a feasible strategy for developing broad-pH-applicable, facile, and on-site colorimetric sensing for pesticide monitoring.

Tumor hypoxia is a major barrier to oxygen-dependent photodynamic therapy (PDT), markedly limiting its therapeutic efficacy in hepatocellular carcinoma (HCC). Herein, a self‑oxygenating and redox-amplifying metal-organic framework (MOF) nanoplatform is constructed by co-loading sorafenib (Sor) and plumbagin (PLB) into a surface galactose functionalized Mn-porphyrinic PCN-224(Mn) (PM) framework to afford SorPLB@Gal-PM for asialoglycoprotein receptor (ASGPR)-mediated HCC targeting. The Mn-porphyrin centers endow SorPLB@Gal-PM with catalase-like activity, enabling in situ decomposition of endogenous H 2 O 2 to generate O 2 and thereby sustaining 1 O 2 -based PDT under irradiation. Meanwhile, Sor/PLB co-delivery, together with PLB-mediated GPX4 suppression, promotes oxidative stress amplification. In hypoxic liver cancer stem cell-like C5WN1 cells, SorPLB@Gal-PM elicits markedly enhanced intracellular ROS upon irradiation, showing approximately 3.4-fold and 2.9-fold higher DCFH-DA signals than SorPLB@Gal-PCN-224 and PM, respectively, accompanied by downregulation of hypoxia-inducible factor-1α (HIF-1α) and glutathione peroxidase 4 (GPX4). In a C5WN1 tumor-bearing nude mouse model, SorPLB@Gal-PM combined with irradiation achieves the most potent tumor suppression with a tumor inhibition rate of 83.70% ± 4.12%. Collectively, SorPLB@Gal-PM provides a hypoxia-adaptive nanoplatform integrating Mn-assisted self‑oxygenation and redox-amplified chemo-PDT for effective HCC therapy.

Single-atom catalysts (SACs) offer ideal active sites for advanced oxidation processes, yet their practical applications are hindered by synthetic complexity, isolated centers, and limited redox and charge-transfer dynamics. Here, we report a scalable synthesis of a Fe–Mn dual-atom catalyst (Fe–Mn/N–C) featuring a symmetric Fe–Mn–N6 coordination structure. This unique configuration establishes a sustainable bimetallic redox cycle that enables efficient activation of peracetic acid (PAA) for pollutant degradation. The catalyst achieves nearly complete removal of sulfamethoxazole (99.9%) with an apparent rate constant of 0.3226 min–1—7.7 and 8.5 times higher than those of Fe/N–C and Mn/N–C counterparts, respectively. Density functional theory calculations reveal that Mn–N coordination promotes electronic delocalization and fine-tunes the electronic structure of adjacent Fe centers, leading to distinct PAA adsorption geometries on Mn and Fe sites that favor the selective formation of hydroxyl radicals (•OH) and singlet oxygen (1O2) species. The optimized Mn d-band center further lowers the energy barrier for 1O2 generation. Moreover, the Fe3+/Fe2+ and Mn4+/Mn3+ redox cycles are coupled through electron transfer between Fe and Mn centers, ensuring self-regeneration of active sites and sustained catalytic stability. The Fe–Mn/N–C catalyst exhibits outstanding activity across a wide pH range, strong tolerance to competing inorganic ions, excellent recyclability, and broad substrate applicability. Collectively, this work establishes a durable bimetallic redox-coupling strategy that leverages electronic structure modulation to realize synergistic oxidation and provides insights for the rational design of robust Fenton-like catalysts for complex environments.

Efficient recovery of nickel, cobalt, and manganese from Ca- and Mg-rich sulfate leachates is essential for battery-grade precursor production. A synergistic solvent extraction (SSX) system combining N,N-bis(4-thiazolylmethyl)octylamine (NNBT) with acidic organophosphorus extractants was developed to achieve coextraction of Ni, Co, and Mn. Among various combinations, the D2EHPA–NNBT system exhibited the highest selectivity and cost efficiency, enabling complete extraction of Ni, Co, and Mn while suppressing Ca and Mg transfer. Multistage countercurrent and scrubbing operations further reduced impurities, producing high-purity Ni–Co–Mn sulfate solutions suitable for battery applications. Thermodynamic and spectroscopic analyses confirmed that synergism originated from selective coordination and cation-exchange interactions. This study demonstrates a practical and scalable route for selective Ni–Co–Mn recovery from impurity-rich sulfate solutions, contributing to the efficient and sustainable hydrometallurgical processing of battery metals.

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.

Multimodal optical anti-counterfeiting plays a vital role in modern commodity circulation. However, most current multimodal anti-counterfeiting materials rely on complex multi-component compounds and costly rare-earth ion doping, which limits their commercial applications. Therefore, achieving multimodal anti-counterfeiting within simple and low-cost compound systems holds promising practical prospects. This work developed luminescent materials with multimodal emission and optical storage capabilities via Mn 2+ single doping and Li-flux modification of an inexpensive and readily available CaO host. Calcium oxide is a common industrial product that can be obtained through simple calcination, laying the foundation for practical commercial applications. The Mn 2+ singly-doped sample enables information writing via ultraviolet light and dual-mode (thermal/optical) readout, a property not shared by the Li-flux modified counterpart. Furthermore, based on the flux effect, Li-flux treatment not only enhances the green emission of Mn 2+ but also introduces deeper traps, extending storage duration and enabling high-temperature readout. Leveraging the differences in optical response and trap distribution between the two materials, a multi-level optical anti-counterfeiting demonstration with dynamic color and temperature-dependent characteristics was constructed. This work provides a new material strategy for developing low-cost, high-security optical anti-counterfeiting and information encryption technologies.

Hierarchical x MCMnO x was fabricated via facile in-situ silane confinement strategy. • Si-O-Mn are formed by the interaction of amorphous siloxane network and MOF precursor. • Mn 4+ + Ce 3+ ⇌Mn 3+ + Ce 4+ cycle forms a dynamic equilibrium to produce oxygen vacancies. • 3MCMnO x shown superior activity for low-temperature NH 3 -SCR with H 2 O/SO 2 resistance. Developing high-efficiency catalysts for the selective catalytic reduction of NO x with NH 3 (NH 3 -SCR) is of great significance for achieving ultra-low NO x emissions. Herein, hierarchical x MCMnO x hollow nanorod hybrids were fabricated via a facile in-situ silane confinement strategy using Ce-doped Mn-BTC modified with MTMS (methyltrimethoxysilane) as the sacrificial template for NH 3 -SCR reaction. Systematic studies demonstrated that the tight chemical interaction between the amorphous siloxane network and the MOF precursor facilitated the highly dispersed distribution of the doped Ce species around the Mn active sites, forming abundant Si-O-Mn interface covalent bonds and strong metal-metal interactions (Mn 4 + + Ce 3+ ⇌ Mn 3+ + Ce 4+ ). Benefiting from the stronger NH₃ adsorption capacity, abundant reactive oxygen species, and surface-enriched hydrophobic methyl groups, the optimized 3MCMnO x promoted the Eley-Rideal (E-R) reaction pathway via strong Si-O-Mn interfacial coupling, achieving a 100% NO conversion rate within the temperature range of 150–300 °C at a GHSV of 36000 h −1 and robust H 2 O/SO 2 tolerance. Furthermore, the universality of this way was verified in analogous Co-based and Cu-based systems. This work opens a new avenue for the design of efficient and durable MOF-derived denitration catalysts for non-electric industries.
