A bimetallic Au–Ag nanoalloy mounted LDH/RGO nanocomposite: a promising catalyst effective towards a coupled system for the photoredox reactions converting benzyl alcohol to benzaldehyde and nitrobenzene to aniline under visible light

The bimetallic surface plasmon chemistry of Au–Ag and the π-carbon skeleton of rGO enhance the exciton concentration and separation over ZnCr-LDH, resulting in notable photocatalytic activity.
