ZnO was incorporated into nano particles of clinoptiloite by ion exchanging the zeolite in a zinc nitrateaqueous solution followed by calcinations process. All raw and modified samples were characterized byXRD, FT-IR, DRS, TG-DTG, SEM, BET and TEM. The prepared catalyst was used in the photocatalyticdegradation of phenylhydrazine (PHZ) and the best experimental parameters were obtained as:0.25 g L-1 of the catalyst, 20 ppm pollutant concentration and pH = 8. The degradation extent wasmonitored by UV–vis spectroscopy and the results were confirmed by HPLC and the chemical oxygendemand (COD).
