Abstract

We introduce a unique material ensemble to boost the photocatalytic activity of m-BiVO₄ by creating dual heterojunction of bismuth oxybromide nanosheets and Pd nanodomains. The m-BiVO₄/BiOBr/Pd ternary composite demonstrates substantially higher photocatalytic activity compared to pure m-BiVO₄. We demonstrate for the first time the use of such visible light photocatalyst in highly efficient degradation of polychlorinated biphenyls.
