Summary: A photoreduction method was used to immobilize Ni single atoms on CdS nanoparticles, forming an electric metal-semiconductor interaction (EMSI) that greatly promoted H2O-to-H-2 conversion under simulated sunlight. The nanocatalyst with 1.25‰ Ni loading achieved the highest conversion rate and photostability, along with improved light absorption capacity and photexciton utilization efficiency. Under alkaline conditions, OH- ions reacted with photogenerated holes to inhibit oxidation and enhance conversion performance. This study provides insights for improving photocatalyst performance through non-noble metallic single-atom cocatalysis.

Summary: Multi-level heterojunction is effective in promoting charge separation and transfer for improved photocatalytic hydrogen evolution. A V2O5/CdS/CuS multi-level heterojunction (VCU) is constructed by introducing V2O5 into a CdS/CuS heterojunction prepared via a one-pot hydrothermal method. The VCU heterostructure combines CdS and CuS as mixed nanoparticles, enabling enhanced electron transfer and increased light absorption. Hydrogen evolution tests demonstrate that VCU exhibits optimal performance with a hydrogen production rate 16.4 times higher than pure CdS. The analysis of binary composite structures elucidates the possible electron transfer process of VCU, unraveling the internal catalytic mechanism. This work expands approaches for photocatalyst mechanism analysis and demonstrates a significant improvement in photocatalytic hydrogen production by multi-level heterostructures.

Summary: Revealing the activation mechanism of nitrate reduction is crucial for designing efficient photocatalysts for nitrate removal. In this study, the performance of photocatalytic nitrate reduction was thoroughly investigated on different crystalline phases of TiO2. It was found that anatase TiO2 exhibited a higher rate of nitrate degradation than rutile TiO2 under simulated sunlight conditions. The possible reaction paths of nitrate reduction on anatase TiO2 were verified through in situ Fourier Transform Infrared (FTIR) and density functional theory (DFT) calculations. This study presents a new perspective on the reaction paths of nitrate photoreduction.

Summary: Hybrid nanoparticles combining plasmonic and catalytic components have potential applications in sunlight-to-chemical energy conversion. Core-satellite structures show higher reaction enhancement under illumination compared to core-shell structures. The difference lies in the excitation of highly localized and asymmetric electric fields, with the core Au particle capturing visible light through localized plasmon resonances and the surrounding Pd satellites transducing the enhanced electric field into catalytic activity.

Summary: This study demonstrates the possibility of using metal-organic frameworks (MOFs) as heterogeneous photocatalysts for hydrogen generation from sustainable resources. Among the MOFs tested, UiO-66(Zr)-NH2 exhibited the highest photocatalytic activity due to its suitable energy level. The photocatalytic activity of UiO-66(Zr)-NH2 can be further enhanced by incorporating small Pt nanoparticles as co-catalysts. The results provide evidence of photoinduced charge separation with Pt@UiO-66(Zr)-NH2, suggesting the potential of MOFs as photocatalysts for solar-driven hydrogen generation.

Summary: In this study, MoSe2 nanoflowers (NFs) were utilized as piezoelectric nanozymes for the dual-driven catalytic eradication of multi-drug-resistant bacterial biofilms. The piezoelectricity of MoSe2 NFs, combined with their enzyme-mimic activity, led to a significant increase in oxidative stress in the biofilms under ultrasound irradiation, resulting in a 4.0 log10 reduction of bacterial cells. In vivo studies showed that the MoSe2 NFs effectively reduced the burden of methicillin-resistant Staphylococcus aureus in mice under ultrasound control. Additionally, the surface coating of antioxidant poly(ethyleneimine) minimized off-target damage and promoted wound healing.

Summary: Single-atom catalysts with adjacent Fe nanoclusters supported on nitrogen-doped carbon aerogels show enhanced oxygen reduction reaction activity and anti-oxidation stability, resulting from increased 3d electron density and decreased magnetic moment of Fe atomic centers. A flexible zinc-air battery using these catalysts achieves remarkable performance, even at -40 degrees C, with high open circuit voltage, power density, and excellent durability after 2300 continuous cycles. These results highlight the significance of electronic manipulation in enhancing the durability of single atom catalysts.

Summary: Development of heterojunction is an effective strategy to enhance the hydrogen production performance of photocatalysts. In this study, a 2D/2D Z-scheme heterojunction-coupled Zn0.4Cd0.6S with g-C3N4 was fabricated using in situ hydrothermal approach. The sheet-on-sheet architecture allowed full contact of heterojunction, facilitating interfacial charge transfer and increasing surface-active sites. Moreover, the Zn-N coordination bond provided a strong interfacial interaction and spatially separated photogenerated charges along the Z-scheme mechanism. The optimal photocatalyst exhibited high hydrogen production rates (7.69 mmol g-1 h-1) under visible-light irradiation without any cocatalysts, four times higher than the g-C3N4 photocatalyst with Pt as a cocatalyst. The catalyst also showed long-term stability of up to 50 hours. Thus, a direct Z-scheme heterojunction with intimate contact and a well-definite bridging chemical bond holds promise for hydrogen generation.
