Integrating Co(OH)₂ nanosheet arrays on graphene for efficient noble-metal-free EY-sensitized photocatalytic H₂ evolution

Abstract

-GR arises from its unique nanosheet array architecture, which can collaboratively expose rich active sites for photocatalytic hydrogen evolution and facilitate the migration and separation of photogenerated charge carriers. It is desired that this study would supply a meaningful direction for the rational optimization of the constitute and structure of cocatalysts to achieve efficient photocatalytic hydrogen generation.
