Nonylphenol photodegradation by novel ternary MIL-100(Fe)/ZnFe2O4/PCN composite under visible light irradiation via double charge transfer process
文献摘要:
Nonylphenol (NP) residues,as a typical endocrine disrupting chemical (EDC),frequently exist in sewage,surface water,groundwater and even drinking water,which poses a se-rious threat to human health due to its bioaccumulation.In order to remove NP,a series of MIL-100(Fe)/ZnFe2O4/flake-like porous carbon nitride (MIL/ZC) was synthesized through in-situ synthesis at room temperature.High performance of ternary MIL/ZC is used to de-grade NP under visible light irradiation.The results show that 30MIL/ZC2 (20 wt.% ZnFe2O4)ternary composite had the best photocatalytic activity (99.84%) when the dosage was 30 mg.Further mechanism analysis shows that the excellent photocatalytic activity of 30MIL/ZC2 could be ascribed to the double charge transfer process between flake-like porous carbon nitride (PCN) and other catalysts in the ternary heterojunction,and the separation of pho-togenerated electron-hole pairs was more effective.In addition,the 30MIL/ZC2 also showed high stability after five cycles of the photodegradation reaction.Furthermore,the active sub-stance (·O2-) was considered to be the main active substance in the NP degradation process.Based on the research results,the possible photocatalytic reaction mechanism of 30MIL/ZC2 ternary composite was proposed and discussed in detail
