The objective of the study was to investigate the effect of process parameters on the photocatalytic degradation of phenol. The ZnO/Fe2O3 nanocomposite photocatalyst was prepared by sol-gel method and characterized using vari-ous instrument techniques. The characterized ZnO/Fe2O3 nanocomposite displayed suitable physico-chemical properties for the photocatalytic reaction. The ZnO/Fe2O3 nanocomposite was employed for the phenol degradation in a cylindrical batch reactor under solar radiation. The photocatalytic runs show that calcination temperature of the ZnO/Fe2O3 nanocomposite, catalyst loading, initial phenol concentration and pH of the wastewater significantly influence the photocatalytic degradation of phe-nol. After 180 min of solar radiation, the highest phenol degradation of 92.7% was obtained using the ZnO/Fe2O3 photocatalyst calcined at 400 �C. This study has demonstrated that phenol degradation is significantly influenced by parameters such as calcination temperature of the ZnO/Fe2O3 nanocompo-site, catalyst loading, initial phenol concentration and pH of the wastewater resulting in highest phe-nol degradation using the ZnO/Fe2O3 nanocomposite calcined at 400 �C, initial phenol concentration of 0.5 mg/L, catalyst loading of 3 mg/L and pH of 3.
