Catalysis of Organic Pollutants Abatement Based on Pt-Decorated Ag@Cu(2)O Heterostructures

Pt-decorated Ag@Cu(2)O heterostructures were successfully synthesized using a simple and convenient method. The Pt nanoparticle density on the Ag@Cu(2)O can be controlled by changing the concentration of the Pt precursor. The synthesized Ag@Cu(2)O–Pt nanoparticles exhibited excellent catalytic performance, which was greatly affected by changes in the Ag@Cu(2)O–Pt structure. To optimize the material’s properties, the synthesized Ag@Cu(2)O–Pt nanoparticles were used to catalyze toxic pollutants and methyl orange (MO), and nontoxic products were obtained by catalytic reduction. The Pt-decorated Ag@Cu(2)O nanoparticles showed excellent catalytic activity, which significantly decreased the pollutant concentration when the nanoparticles were used for catalytic reduction. The redistribution of charge transfer is the nanoparticles’ main contribution to the catalytic degradation of an organic pollutant. This Pt-decorated Ag@Cu(2)O material has unique optical and structural characteristics that make it suitable for photocatalysis, local surface plasmon resonance, and peroxide catalysis.
