摘要
The photocatalytic performances in the photocatalytic degradation of tetracycline hydrochloride(TC) of ZnSb2O4 and ZnSb2O6 synthesized by hydrothermal method were explored.The effects of synthesis conditions including reaction temperature, reaction time, precursor solution pH, and the amount of hydrazine hydrate on the photocatalytic activity were discussed.The ZnSb2O4 and ZnSb2O6 photocatalysts prepared under optimal conditions exhibited similar photocatalytic activities for the degradation of TC. However, the areal photoctalytic activity of ZnSb2O4 was 12 times higher than that of ZnSb2O6 because of their different electronic and geometric structures. The photocatalytic degradation mechanisms of TC over ZnSb2O4 and ZnSb2O6 were proposed. Our work will facilitate the development of composite oxides consisting of p-block metal ions as new semiconductor photocatalysts.
