Summary: The interfacial Pt-S bonds are designed via an in situ photoreduction to anchor Pt sub-nanoclusters on the tandem homojunction CdS. The optimized Pt-0.02-CdSx-T photocatalyst exhibits impressive hydrogen evolution performance and an apparent quantum yield much higher than that of pristine CdS. Systematic investigations reveal that the interfacial Pt-S bonds and homojunction CdSx-T play crucial roles in facilitating photocarrier transfer, electron transfer kinetics, and H* adsorption capacity.

Summary: In this study, a Zn2+ and Ni2+ modified carbon hydrogen evolution cocatalyst (ZnNi-C) was synthesized and immobilized onto the surface of CdS for photocatalytic hydrogen evolution. The optimized CdS@ZnNi-C photocatalyst exhibited a hydrogen evolution rate of 15.7 mmol/h/g and an apparent quantum efficiency (AQE) of 31.4% at 420 nm, which were significantly higher than those of other modified carbon cocatalysts. The improved catalytic performance was attributed to the co-anchored Zn2+ and Ni2+ in carbon layers, which resulted in a favorable Gibbs free energy for hydrogen evolution.

Summary: This study demonstrates the advantages of using a non-noble metal-based ZIF-67 derivative, Co-N-C, as a co-catalyst for the in situ growth of spherical CdS via simple one-step hydrothermal method. The large specific surface area of Co-N-C prevents the agglomeration of CdS and weakens the photocorrosion phenomenon. The Co-N-C/CdS composite exhibited a hydrogen generation activity of 905 mu mol g-1 h-1 under visible light irradiation, which was 6 times higher than that of pure CdS, with excellent stability. Thus, this work highlights the potential of CdS binding MOF derivatives in constructing composite photocatalysts with enhanced dispersibility and hydrogen production activity.

Summary: In the past decade, photocatalytic hydrogen evolution from metal-loaded TiO2 has received significant attention. This study compares size-selected Ni and Pt clusters as co-catalysts on a TiO2(110) single crystal and investigates the size- and coverage-dependent effects on the catalyst performance. Larger clusters and higher coverages of Ni enhance the product formation rate, while Pt co-catalysts exhibit a stable and higher activity, but size-specific effects need to be considered.

Summary: In this study, highly dispersed PdS nanoparticles were decorated on ultrathin In2S3 nanosheets as an efficient hole co-catalyst, forming an intimate interface structure. Due to the high hole capture capacity of PdS and the assistance of the internal electric field, the photogenerated charge carriers can be effectively separated and protect the semiconductor photocatalyst In2S3 from photo-oxidation. The experimental results showed that the hydrogen production rate of 3PdS/In2S3 nanocomposite was 149.8 times higher than that of pristine In2S3 nanosheets and 13.3 times higher than In2S3 decorated with Pt. This study provides a new approach to enhance the efficiency of photocatalytic energy conversion.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
