Cellulose acetate-Ce/Zr@Cu catalyst for the degradation of organic pollutant.

In the present work, Cu nanoparticles were stabilized on ceria/zirconia (Ce/Zr@Cu), cellulose acetate (CA@Cu), and a thin film of cellulose acetate embedded ceria/zirconia (CA-Ce/Zr) designated as CA-Ce/Zr@Cu. In the presence of a reducing agent, all the catalysts revealed excellent catalytic efficiency in aqueous media for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) and degradation of cationic dyes methylene blue (MB) and rhodamine B (RB). Different order of equations were applied to determine the adjacent R value and rate constant.
