The micro/nano-structure composite SiO2@Ag/AgCl was employed as a low cost photocatalyst for the degradation of RhB in aqueous solution under visible light irradiation, which exhibited excellent photocatalytic performance and stability.
BiVO4 supported Ag–AgBr heterostructures were fabricated by a designed three-step method and then used as an efficient visible light driven plasmonic photocatalyst to degrade organic dye.
