Boosting photocatalytic hydrogen production of CdS/BiVO4 nanoplates by transferring in-plane plasmon resonant energy of gold nanoparticles

Abstract

A free-standing plate-type plasmon-enhanced Z-scheme photocatalytic system has been established via CdS deposition on Au-decorated BiVO4 nanoplates (CdS/Au on BiVO4). Through the enhancement from in-plane plasmon resonant energy transfer of gold, the hydrogen evolution rate of CdS/Au on BiVO4 was enhanced about 7.7 times higher than that of the gold-free photocatalyst.
