Thin layer chitosan-coated cellulose filter paper as substrate for immobilization of catalytic cobalt nanoparticles

A facile approach utilizing synthesis of cobalt nanoparticles in green polymers of chitosan (CS) coating layer on high surface area cellulose microfibers of filter paper (CFP) is described for the catalytic reduction of nitrophenol and an organic dye using NaBH4. Simple steps of CFP coating with 1 wt% CS aqueous solution followed by Co2+ ions adsorption from 0.2 M CoCl2 aqueous solution were carried out to prepare pre-catalytic strips. The Co2+...
