Ultrathin Bi2Se3/CdS composite for efficient photocatalytic hydrogen evolutionviahigh interfacial charge separation and photothermal effect

Ultrathin Bi 2 Se 3 nanosheets/CdS nanoparticles were prepared, which display excellent photocatalytic H 2 activity, ascribed to the synergistic mechanism of the unusual transfer process of high-energy electrons and the photothermal effect.
