摘要：AgX (X - Cl, Br, I)-modified Ag2MoO4 crystals with a mosaic style can be produced in quantity through an in situ composite method. Different AgX-Ag2MoO4 composite materials (CMs) exhibited various photocatalytic abilities due to their diverse properties, among which AgBr-Ag2MoO4 CMs performed best. The catalytic efficiency of AgBr-Ag2MoO4 CMs was enhanced 149 times compared to pure Ag2MoO4, degrading organic dyes within just 2 min. We have proposed a brand new theory, "the mosaic structure effect", to explain the achievement of this high efficiency catalysis. This mosaic structure effect contributed most to the artistic and regular coating, the tight inlay of the AgBr and Ag2MoO4, as well as to the increase in the recombination lifetime of the carrier. This study exhibited a certified record efficiency in degrading organic dyes and antibiotics.
