Summary: Researchers proposed a novel method to deposit sub-10 nm metallic Ni2P particles on the surface of graphitic carbon nitride (CN) for enhanced H-2 generation under visible light. The Ni2P-modified CN showed improved optical properties and electron shuttling capability, leading to a significantly increased H-2 production. However, the catalytic activity decreased after multiple reaction cycles due to the photo-corrosion of the Ni2P cocatalyst.

Summary: Designing S-Scheme heterojunctions can effectively improve the photocatalytic performance for hydrogen evolution by avoiding futile charge transport routes. In this study, a twin S-Scheme heterojunction consisting of graphitic C3N4 nanosheets, hydrogen-doped rutile TiO2 nanorods, and anatase TiO2 nanoparticles was proposed. The catalyst exhibited a high hydrogen evolution rate of 62.37 mmol g(-1) h(-1) and an apparent quantum efficiency of 45.9% at 365 nm. The significant enhancement of photocatalytic performance was attributed to the efficient charge separation and transfer facilitated by the unique twin S-Scheme structure. In situ X-ray photoelectron spectroscopy (XPS), electron spin resonance (ESR) spin-trapping tests, and other characterizations confirmed the charge transfer route in the twin S-Scheme.

Summary: Enhancing photogenerated charge transfer is an effective way to improve the photocatalytic activity of hydrogen production. The good electrical conductivity of ZnCo2O4 facilitates charge transfer, while CoS serves as the active site for the thermodynamically favorable hydrogen production reaction. The composite of p-type ZnCo2O4 and n-type CoS shows a strong surface interaction, with a more negative surface potential that favors H+ adsorption. The construction of an S-Scheme heterojunction accelerates charge transfer and is the main factor contributing to enhanced photocatalytic hydrogen evolution performance. In situ XPS analysis provides strong evidence for the charge transfer mechanism of the S-Scheme heterojunction.
