Developing advanced photothermal effect photocatalysts to maximize solar utilization receives increasing attentions in photocatalytic H 2 production. Herein, a Ni-doped Zn 0.7 Cd 0.3 S (Ni-ZCS-20) integrating photothermal material and photocatalyst was constructed via simple one-step hydrothermal method. Successful incorporation of Ni into Zn 0.7 Cd 0.3 S was confirmed by various characterization techniques including XRD, XPS, SEM and TEM. Under photothermal-assisted condition, the Ni-ZCS-20 offered a superfast H 2 generation rate, reaching as high as 183 mmol/g·h, which exhibited enormous advantages over existing photocatalysts. Detailed mechanism explorations verified that such a high H 2 generation rate of Ni-ZCS-20 could be attributed to the lowed H 2 generation overpotential, broadened light absorption region, and promoted photogenerated carrier separation originating from the Ni doping. In addition, the doped Ni partly substituted the Zn in Ni-ZCS-20, providing an extra channel for photogenerated electrons and efficiently hindering the recombination of electron-hole pairs. Density functional theory (DFT) calculations demonstrated that Ni incorporation into ZCS effectively tailored its electronic structure, enhanced surface electron-supply capability, and optimized hydrogen adsorption, thereby leading to superior catalytic performance of Ni-ZCS toward HER. This finding provides valuable guidance for constructing photothermal effect materials to exploit full spectrum solar in photocatalytic H 2 evolution.

Enhancing the carrier separation efficiency and charge transport properties of polymeric carbon nitride (PCN) has been a major focus of research. Extensive interest has been directed toward its modification and functionalization. In this study, a molten-salt approach was employed to simultaneously introduce cationic (K + ) and anionic (–C≡N) species, enabling the one-step synthesis of highly crystalline PCN with significantly improved carrier separation and charge transport efficiencies. Comprehensive experimental characterization and theoretical calculations reveal that the coupling interaction between the cations and anions substantially increased the localized charge distribution, thereby facilitating exciton dissociation. Moreover, the incorporation of –C≡N and K + ion pairs enhanced the adsorption and activation of O 2 , driving the two-electron oxygen reduction reaction (2e – ORR) to produce H 2 O 2 , exhibiting a remarkable 46.6-fold increase over unmodified PCN. This work provided valuable insights into the critical role of cation-anion pairs in enhancing exciton dissociation, paving the cost-effective way for photocatalysts toward efficient solar energy conversion and high-value-added chemicals artificial photosynthesis.

Photocatalytic oxygen reduction to produce hydrogen peroxide (H 2 O 2 ) represents a sustainable and environmentally friendly approach for H 2 O 2 photosynthesis, while the activity is still severely limited by the slow charge and proton dynamics. Herein, we constructed CdS-based homojunctions which composed of cubic and hexagonal phases by simply capping of CdS with 3-mercaptopropionate (MPA) for visible light-driven H 2 O 2 production. Characterization results suggested the commensalism and intimate contact of cubic and hexagonal phases in the resulted MPA-CdS photocatalysts, which improved light harvesting, and boosted the charge separation and transfer at homojunction interface. MPA capping agents on CdS surfaces also served as proton relays and localize protons near the active sites towards efficient photocatalytic O 2 reduction. Thus, the problems caused by both slow charge transfer and sluggish proton dynamics can be resolved. Furthermore, the coordination between MPA and Cd 2 + ions prevented Cd 2+ leaching into solution, which retarded the oxidative holes induced photocorrosion of CdS due to the Cd 2+ confinement effect. Consequently, the obtained MPA-CdS-x catalysts, especially, MPA-CdS-6, achieved excellent photocatalytic H 2 O 2 production rate (1250.17 µmol g⁻¹ h⁻¹) under visible light from H 2 O and O 2 without any sacrificial agents, which was 2.2 times higher than its bare CdS counterpart (580.07 µmol g⁻¹ h⁻¹). This study proposes a simple and excellent method to enhance charge and proton transfer for high-performance H 2 O 2 green production.

Metal–organic frameworks (MOFs) have received widespread attention in various energy related applications due to their unique structural characteristics. Nevertheless, the inherent low electronic conductivity of MOFs is a major limitation for their competitive activity. Herein, we synthesized a self-standing NiFe MOF@Ni3S2 core–shell hierarchical heterostructure through using Ni3S2 grown on nickel foam (NF) as a semisacrificial template, in which the highly conductive Ni3S2 nanosheets core endows the hybrid with rapid charge transfer capability, and the bimetallic NiFe MOF nanosheets provide abundant exposed active sites. Benefiting from the structural and compositional advantages, the enhanced electrocatalytic activity of the as-obtained NiFe MOF@Ni3S2/NF has been achieved toward alkaline oxygen evolution reaction (OER). As a result, the NiFe MOF@Ni3S2/NF only requires overpotentials of 177 and 219 mV to yield OER current densities of 10 and 100 mA cm–2, respectively, and exhibits a very small Tafel slope of 24.1 mV dec–1 and high durability, making it among the most efficient earth-abundant OER catalysts. This study will inspire further construction of MOF-based nanocomposites for applications in electrochemical renewable energy systems.

In this work, CuS@PVP nanospheres with large specific surface areas were successfully prepared via a one-step hydrothermal process by introducing the polyvinylpyrrolidone (PVP) surfactant into the precursor and modulating its dosage. As an anode material for aqueous zinc-ion batteries, the prepared CuS@PVP can shorten the transmission distance of Zn2+ and electrons and increase the number of reaction sites. CuS@PVP with 0.2 g of PVP added has a specific capacity of 305.4 mAh g–1 at a current density of 0.2 A g–1 and an ultralong cycle life of 2000 cycles at a current density of 2 A g–1. In addition, the capacity of the CuS@PVP||Na–MnO2 full cell is as high as 220.0 mAh g–1 at a current density of 0.2 A g–1, and the capacity retention rate is 85.9% after 100 cycles. The results prove that CuS@PVP is an excellent choice as an anode material for aqueous zinc-ion batteries.

A tetrazine-functionalized zirconium MOF, UiO-68-TZDC (isostructural with UiO-68-TPDC), is constructed through a one-pot solvothermal synthesis for the selective recovery of Au(III) from acidic chloride media, using UiO-68-TPDC as a tetrazine-free, isostructural counterpart. The obtained crystalline materials possess good thermal stability. UiO-68-TZDC shows a saturated Au(III) uptake of 404.4 mg g−1, which is significantly higher than that of UiO-68-TPDC (114.5 mg g−1), and comparable or superior to many reported N- and S-functionalized Zr-MOFs. The adsorption kinetics follow the pseudo-second-order model with multi-stage intraparticle diffusion, indicating combined control by chemisorption and diffusion. UiO-68-TZDC displays pronounced selectivity for Au(III) over Fe(III) and Cu(II) and retains more than 70% of its initial capacity after several adsorption–desorption cycles. Structural and spectroscopic analyses reveal the formation of crystalline Au0 domains and surface Au(III) and Au(I) species, directly indicating a partial reduction process driven by the electron-rich tetrazine linker, as evidenced by significant shifts in the electronic states of the nitrogen sites. These results support a cooperative “preconcentration-coordination-reduction” mechanism and demonstrate that tetrazine linker engineering in robust UiO-68 frameworks is an effective strategy for developing high-performance adsorbents for Au(III) recovery from acidic gold-containing waste streams.

Crystal plane engineering and the piezoelectric effect show promise for enhancing hydrogen evolution reaction performance, yet potential synergistic effects between them remain unclear. In this study, NiS 2 /CdS composites dominated by CdS (002) crystalline facet were successfully synthesized and used for piezoelectric photocatalytic hydrogen evolution. Under piezoelectric conditions, CdS72 with a high (002) facet ratio demonstrated a 4.56 times improvement in hydrogen evolution performance compared to pure light irradiation, while CdS24 with a lower (002) facet ratio showed a 2.8 times enhancement. Notably, the optimized sample NiS 2 -5/CdS72 reached a piezoelectric photocatalytic hydrogen evolution rate of 15.67 mmol g −1 h −1 , which is 4.54 times higher than that of NiS 2 -5/CdS24 with pure irradiation. Through piezoelectric force microscopy (PFM) and finite element simulations, we revealed that the (002) enriched CdS72 generates stronger piezoelectric fields, which synergistically accelerate photogenerated charge separation as evidenced by enhanced piezoelectric photocurrent responses. The combination of the piezoelectric effect and crystalline face engineering enables structural design and broad application of highly active photocatalysts.

Rechargeable magnesium-metal batteries (RMBs) have been regarded as promising candidates for energy storage systems owing to the high volumetric capacity, favorable safety profile, and high crustal abundance of Mg. However, the performance of RMBs is constrained by sluggish Mg2+ diffusivity in the cathode materials, leading to a substantial electrochemically inactive interior volume. Herein, we achieved the fast solid-state diffusion of Mg2+ by constructing an ordered shell-to-core built-in electric field (BEF) via orientated MoS2/MoO2 coaxial heterojunction nanotube arrays, giving rise to high capacity even at low temperatures. Benefiting from the easy transport and deep intercalation depth of Mg2+, the obtained cathode delivered an outstanding rate performance (312 mAh g–1 at 0.05 A g–1 and 115 mAh g–1 at 5 A g–1) and long-term durability with an average fade of 0.0025% per cycle over 4000 cycles. Impressively, a capacity of 150 mAh g–1 was still retained at 0.05 A g–1 even at −20 °C because of the maintained largely promoted Mg2+ diffusivity of 10–10 cm2 s–1 at this low temperature, which is promising but rarely reported for RMBs.

As a potential high-safety and high-energy-density technology, lithium sulfide has been extensively studied as a cathode material for lithium–sulfur batteries under room temperature conditions. However, limited by its intrinsic characteristics of low electronic conductivity and high activation energy barrier, conventional Li2S cathodes struggle to overcome the activation energy barrier at low temperatures, resulting in scarce research on their application below zero. Specifically, studies on operation at −20 °C are nearly nonexistent. Herein, a synergistic strategy combining molybdenum carbide support adsorption and cobalt metal catalysis is proposed for low-temperature performance investigation. Via a lithiation reaction, Li2S@MoC–Co nanocomposites are fabricated by in situ synthesizing Li2S nanoparticles, introducing MoC as the support, and incorporating Co metal. When assembled into batteries with Li2S@MoC–Co as the cathode and metallic lithium as the anode, the activation energy barrier is reduced to 2.41 V at room temperature, exhibiting excellent electrochemical performance. A high initial discharge capacity of 1100 mAh g–1 is achieved at 0.1 C, and a discharge capacity of 430 mAh g–1 is retained after 200 cycles at 0.5 C. Even at −20 °C, Li2S is almost fully activated during the first charging cycle, delivering a discharge capacity of 360 mAh g–1 at 0.05 C. Moreover, a capacity retention rate of 92% is maintained after 300 cycles at 0.5 C. This work realizes high output and high-capacity retention of Li2S at −20 °C, providing a new paradigm for the development of low-temperature Li2S-based batteries.

Copper-based electrocatalysts are regarded as highly efficient electrocatalysts due to their low cost and environmental friendliness. However, their practical application in water splitting remains severely limited by intrinsic drawbacks such as inferior electron transfer kinetics and moderate catalytic activity. Herein, we synthesized copper oxysulfide (CuSxO1–x) flake-like nanoflowers through a redox reaction and explored their application as efficient electrocatalysts for the oxygen evolution reaction. As expected, compared to the original CuS, the copper oxysulfides exhibited superior OER activity and stability, showing a remarkably low overpotential of 206 mV at a benchmark current density of 10 mA cm–2 for the OER. This study elucidates the reconstruction of copper oxysulfide electrocatalysts during the oxygen evolution reaction through in situ ATR-IR measurements. The facilitated formation of reaction intermediates and accelerated reconstruction kinetics during the structural evolution of copper oxysulfide synergistically contribute to its enhanced oxygen evolution reaction performance.

Cobalt disulfide (CoS2) features highly active catalytic sites and is regarded as a promising candidate for electrocatalytic hydrogen evolution. In this study, molybdenum-doped cobalt disulfide (CoS2:Mo) was synthesized via a facile hydrothermal approach. XRD analysis confirms that the obtained samples crystallize in a cubic pyrite structure, with diffraction peaks consistently shifting towards lower angles. SEM characterization reveals that the samples exhibit microrod-like morphologies with an average size of approximately 1 μm. Integrated analyses from XRD, XPS, and EDS mapping demonstrate that Mo is uniformly distributed across the surface and successfully doped into the CoS2lattice. Electrochemical measurements indicate that the CoS2:Mo sample delivers a low overpotential of 122 mV and a Tafel slope of 128 mV dec−1at a current density of 10 mA cm−2in alkaline media, significantly surpassing the performance of pure CoS2and MoS2. Moreover, the CoS2:Mo exhibits an enhanced double-layer capacitance, with a Cdlvalue of 2.72 mF cm−2, superior to that of pure CoS2(1.63 mF cm−2) and MoS2(0.31 mF cm−2). Mo doping enhances conductivity and active sites, thereby boosting electrocatalysis. This work presents an effective strategy for the development of cost-efficient and high-performance non-precious metal electrocatalysts.

Bifunctional materials present a promising route to develop advanced devices, yet the dual performance of CoNi2S4nanosheets anchored on a porous scaffold is seldom reported. Herein, we propose a rational fabrication strategy to construct a three-dimensional hierarchical electrode via the in-situ growth of densely aligned CoNi2S4nanosheets on a conductive fabric scaffold. This integrated porous architecture concurrently offers an ultrahigh specific surface area, efficient mass transport, and rapid electron conduction. As a supercapacitor, the electrode achieves a high areal capacitance of 3198 mF cm−2at 4 mA cm−2and retains 98.1% of its initial capacitance after 1000 cycles at 20 mA cm−2. As a non-enzymatic glucose sensor, it exhibits outstanding selectivity (<4.1% interference), high sensitivity (1049 μA mM−1cm−2), a wide linear range (1–8 mM), and a low detection limit (1 μM). These results highlight the significant potential of this binder-free, scaffold-supported nanosheet design for advancing integrated energy storage and biosensing systems.
