Summary: In this study, a plasmonic catalyst Au-Pt-SiC was prepared by introducing Pt-Si bonds on the SiC surface, creating an excellent channel for efficient photo-electron transfer. The localized surface plasmon resonance effect of Au further activated the Pt-Si bonds and motivated a high-efficient photo-electron transport channel among Au, Pt, and SiC. The LSPR of Au also enhanced light absorption and broadened the range of light absorption.

Summary: A novel hierarchical Au/black phosphorus nanosheets/ZnIn2S4 (Au/BPNSs/ZIS) heterojunction photocatalyst was synthesized by growing ZnIn2S4 (ZIS) nanosheets on black phosphorus nanosheets (BPNSs) and depositing Au nanoparticles on the ZIS surface. The optimized Au/BPNSs/ZIS exhibited a significantly higher hydrogen evolution rate than pure ZIS and few-layer BPNSs. The improved photocatalytic performance of BPNSs/ZIS was attributed to the formation of Zn-P bonds and the interface electric field that facilitated interface charge transfer, while the deposition of Au nanoparticles formed Schottky junctions and further enhanced the photocatalytic activity. This work provides a new approach for developing BP-based heterojunctions in photocatalysis.

Summary: Constructing heterostructures on plasmonic photocatalysts can enhance charge separation, but the mechanism of interface charge transfer is not well understood. In this study, plasmonic Au and metal-organic frameworks (MOFs) heterostructures were fabricated and the charge transfer mechanism was explored. It was found that hot electrons could transfer across the Au/MOF interface and be captured by the MOF structure, while hot holes tended to transfer to and be trapped at the organic ligand. The spatially separated electrons and holes exhibited improved photocatalytic activity. This work demonstrates the importance of versatile functionalization of MOF structures for interface charge transfer on plasmonic photocatalysts.

Summary: Due to their sluggish kinetics, it is urgent to develop highly efficient anode materials for electrocatalytic oxygen evolution reactions. In this work, Ce-doped amorphous Ni(OH)x was constructed on Cu(OH)2 nanorods via electrodeposition. The Ce dopant facilitated charge transfer from Ni to O, resulting in Ni3+ with a higher valence state that served as active sites with more intrinsic activity. Additionally, the Ce dopant reduced charge transfer resistance, leading to faster charge transport during the OER process. The obtained sample exhibited excellent OER performance with an overpotential of 225 mV at 10 mA cm-2 and stable operation at 100 mA cm-2 for 50 h.
