Abstract
A method of forming a nanomaterial catalyst mesh and a nanomaterial catalyst mesh formed by the method. The nanomaterial catalyst mesh comprises a copper support mesh and a nanoparticle layer disposed on the copper support mesh. The nanoparticle layer comprises Cu2O and CuO. The method involves treating the copper mesh support with a plant extract to form a treated mesh and annealing the treated mesh at 210 to 500° C. The nanomaterial catalyst mesh is used in a method of photodegrading an organic pollutant, preferably a dye, involving hydrogen peroxide and visible light.
