Synthesis of CuP/SnO composites for degradation of tetracycline hydrochloride in wastewater.

Antibiotic drugs have become dominating organic pollutants in water resources, and efficient removal of antibiotic drugs is the priority task to protect the water environment. CuP/SnO photocatalysts of various CuP loadings (10-40 wt% CuP) were synthesized using a combination of hydrothermal synthesis and a partial annealing method. Their photocatalytic activity was tested for tetracycline hydrochloride (TC-HCl) degradation under visible light irradiation.
