Pyramid SnO/CeO2 nano-heterojunction photocatalysts were successfully synthesized via a facile hydrothermal method. The structural characterizations were investigated by using common characterization tools. The content of SnO affected the morphology and photocatalytic performance of SnO/CeO2 nano-heterojunctions. With the increase of SnO content, the morphology of samples changed from sphere to pyramid. The photocurrent of SnO/CeO2 (1:6) sample was about 36 times than that of pure CeO2. With SnO/CeO2 (1:6) as the photocatalyst, the degradation rate of tetracycline (TC) was 99% within 140 minutes under visible light and after 5 cyclic tests, the photocatalytic efficiency of TC remained 98%, which suggested that SnO/CeO2 (1:6) nano-heterojunction had a high photocatalytic efficiency and stable photocatalytic performance. These results indicated that SnO/CeO2 (1:6) nano-heterojunction possesses broad prospects for industrial application.
