Application of Zn1?xCdxS Photocatalyst for Degradation of 2-CP and TC, Catalytic Mechanism

Zn1?xCdxS catalysts with Zeolitic Imidazolate Framework-8 (ZIF-8) as the precursor were successfully prepared by ion exchange method, and ability electrochemical properties of a series ZIF-8, ZnS in photocatalytic degradation 2-CP TC investigated. Doping Cd ions was able to modulate band gap width improve utilization visible light photocatalyst. The nanocage hollow structure have better response. removal pollutants up 90% under optimal conditions. Using Peroxymonosulfate (PMS)-assisted system efficiency 2-chlorophenol tetracycline hydrochloride light, we present possible mechanism photocatalyst for persistent PMS-assisted photocatalysis. Four active species, O2?, h+, -OH, SO4•?, can be generated degrade activation. high activity stability provides feasible approach catalytically remove from aqueous solutions
