Fabrication of a novel bifunctional material of BiOI/Ag3VO4 with high adsorption-photocatalysis for efficient treatment of dye wastewater

The dye tended to adsorb on the surface of 30 wt% BiOI/Ag3VO4 by the lone pair electrons of nitrogen atom due to the electrostatic interaction. The electron-hole pairs were efficiently separated after the Ag3VO4 hybridized by BiOI.
