Graphene Photocatalytic Catalyst Preparation and Properties of Composite Materials Research

Abstract

Using a pan of the Ag/TiO2/rGO ternary composites, including ethanol as solvent, not only as a reductant in GO with the reduction of silver nitrate, the addition of ammonia water can not only catalytic hydrolysis TBOT to TiO2 can also form with silver nitrate silver ammonia solution is conducive to the reduction of silver nitrate. And the GO surface exist a large amount of oxygen-containing groups can provide nucleation points for the growth of the nanoparticles. Can control the dosing raio of TBOT and GO different morphology of TiO2/rGO composite material is prepared. Photocatalytic degradation of methylene blue test studied Ag modified enhanced the photocatalytic activity of TiO2 light influence.
