In this investigation, a novel type of zinc oxide supported on clinoptilolite zeolite ZnO /Clinoptilolite (ZnO/CP) nanophotocatalyst was prepared based on the solid-state dispersion (SSD) method. The prepared nanophotocatalyst was characterized with XRD, BET and SEM techniques. As an application, the photocatalytic degradation of malachite green dye (MG) in water under UV irradiation was studied. The results show that the ZnO/CP is an active nanophotocatalyst and the maximum effect of MG photodegradation was observed at 10 wt.% ZnO, 90 wt% Clinoptilolite. Based on the obtained results, a first-order reaction with k = 0.0075 min-1 was concluded. The effects of some parameters such as pH, amount of photocatalyst, and temperature were also examined. Finally, a mechanism was introduced for MG.
