Plasmonic Metal/Semiconductor Heterostructure for Visible Light-Enhanced H₂ Production.

ABSTRACT: A plasmonic Ag/Bi₂WO₆ heterostructure, having Ag NPs deposited on Bi₂WO₆, is obtained by a hydrothermal and photodeposition method. The synthesized Ag/Bi₂WO₆ composite exhibits strong visible light absorption with a localized surface plasmon resonance (LSPR) and shows an enhanced photoabsorption property. It is demonstrated that such a Ag/Bi₂WO₆ heterostructure shows excellent plasmon-enhanced photocatalytic activity in the dehydrogenation of ammonia borane (NH₃BH₃) solution under visible light irradiation, which is due to the results from the synergetic effect between Ag NPs and emerging W⁵⁺ ions. More importantly, the performance of a Ag/Bi₂WO₆ hy
