Photoactive WS₂ nanosheets bearing plasmonic nanoparticles for visible light-driven reduction of nitrophenol

Abstract

Semiconducting WS2 nanohybrids with different sizes of silver nanoparticles are designed via amine-assisted in situ reduction and growth of Ag(+) ions. These nanohybrids exhibit characteristic photocatalytic activity for the reduction of 4-nitrophenol as a function of their structure.
