Selenium-enriched amorphous NiSe1+x nanoclusters as a highly efficient cocatalyst for photocatalytic H2 evolution

Duoduo Gao et al.

Summary: In this study, selenium-enriched amorphous NiSe1+x nanoclusters were integrated with TiO2 to enhance the hydrogen-generation rate. Compared to crystalline nickel selenide, amorphous NiSe1+x exhibited more unsaturated active Se atoms, leading to higher hydrogen-production activity. The enriched Se-mediated mechanism was proposed to explain the boosted hydrogen-generation rate of aNiSe(1+x)/TiO2.
