     a composite semiconductor agbr/ag5p3o10 heterojunction has been synthesized by a simple one-step ion-exchange process in br ionic liquids. all the as-obtained agbr/ag5p3o10 heterojunctions were characterized by x-ray powder diffraction (xrd), scanning electronic microscopy (sem), transmission electronic microscopy (tem), brunauer–emmett–teller (bet), uv–vis absorption spectroscopy (uv–vis), photoluminescence (pl), and surface photovoltage (sps) techniques. the as-prepared agbr/ag5p3o10 heterojunctions intensively absorb in the visible light region. the effects of different conditions on the photocatalytic properties were investigated systematically. the agbr/ag5p3o10 heterojunctions exhibited an enhanced photocatalytic activity than the individual ag5p3o10 did in the degradation of methylene blue (mb) under visible-light irradiation. much more radical dotoh radicals were found in the agbr/ag5p3o10 system in comparison with those in ag5p3o10 alone by analyzing the formed radical dotoh radicals under visible light radiation. the sps measurement shows that the sps amplitude of agbr/ag5p3o10 heterojunctions was higher than that of ag5p3o10, which indicates the higher charge separation efficiency of agbr/ag5p3o10 heterojunctions. based on the above experimental results, the kinetic data and the photocatalytic mechanism of the agbr/ag5p3o10 heterojunctions were discussed in detail.
