Construction of ternary CuO/CuFe2O4/g-C3N4 composite and its enhanced photocatalytic degradation of tetracycline hydrochloride with persulfate under simulated sunlight
文献摘要:
In this study,a graphitic carbon nitride (g-C3N4) based ternary catalyst CuO/CuFe2O4/g-C3N4 (CCCN) is successfully prepared thorough calcination method.After confirming the structure and composition of CCCN,the as-synthesized composites are utilized to activate persulfate (PS) for the degradation of organic contaminant.While using tetracycline hy-drochloride (TC) as pollutant surrogate,the effects of initial pH,PS and catalyst concen-tration on the degradation rate are systematically studied.Under the optimized reaction condition,CCCN/PS is able to give 99% degradation extent and 74% chemical oxygen de-mand removal in assistance of simulated solar light,both of which are apparently greater than that of either CuO/CuFe2O4 and pristine g-C3N4.The great improvement in degradation can be assignable to the effective separation of photoinduced carriers thanks to the integra-tion between CuO/CuFe2O4 and g-C3N4,as well as the increased reaction sites given by the g-C3N4 substrate.Moreover,the scavenging trials imply that the major oxidative matters involved in the decomposition are hydroxyl radicals (·OH),superoxide radicals (·O2-) and photo-induced holes (h+).
