In this paper, CuO/ZnO photocatalyst (CuO loadings 0-10 wt.%) was prepared and evaluated for ammonia removal from aqueous solution under solar light excitation. The photocatalytic activity of CuO/ZnO photocatalyst was highly dependent on the CuO loading, with 5 wt.% CuO achieved optimal removal of ammonia (about %89). The effect of experimental parameters like initial ammonia concentration and solution pH were studied. After 3 hours of irradiation, the maximum removal of ammonia was equal to 99% in pH=10.5. The photocatalytict degradation of ammonia is decelerating with increase initial ammonia concentration
