Synthesis and characterization of AgBr/AgNbO3 composite with enhanced visible-light photocatalytic activity

► The novel AgBr/AgNbO3 composite was synthesized by two-step method. ► The photo-degradation process followed a pseudo-first-order reaction. ► The AgBr/AgNbO3 exhibited a higher photocatalytic activity than the pure AgNbO3. ► AgBr was doped to promote the separation of photo-generated electron-hole.
