摘要: A novel 3D structure Ag/p-Ag 2 S/n-BiVO 4 plasmonic pn heterojunction photocatalyst was successfully fabricated via a depositing p-type Ag 2 S on n-type BiVO 4, followed by light reduction. In this innovative plasmonic pn heterojunction photocatalyst strcture, pn heterojunction can play the role of suppression of charge recombination, and surface plasmon resonance of Ag can enhance the absorption of visible light confirmed by finite difference time domain (FDTD) simulations method. For the photocatalytic oxidation of …
