The enhancement of CdS ultrathin nanosheets photocatalytic activity for water splitting via activating the (001) polar facet by hydrogenation and its charge separation mechanism

The photocatalytic H 2 evolution activity of the CdS nanosheets with exposed {001} facets were significantly improved by hydrogenation. Photocatalytic H 2 evolution mechanism of charge separation driven by Es between CdS {001} polar faces are proposed.
