Synthesis and characterization of nano Ag/Pt and methyl violet co-doped sol–gel porous material

Nano Ag/Pt and methyl violet (MV) co-doped sol–gel substrates have been prepared and characterized by spectral and microscopic techniques. MV was encapsulated in the sol–gel medium along with the bimetal nanoparticles and the resultant materials were compared. MV adsorbed on the surface of nanometal particles and encapsulated into the substrate of both is proposed as a scheme. Photodegradation of four different dyes (MV, methyl green, malachite green and Congo red) as probes, by prepared only bimetal doped substrate is examined and discussed to understand the mechanism.
