In this work,Z-scheme V205 loaded fluorinated inverse opal carbon nitride(IO F-CN/V205)was synthe-sized as a product of ternary collaborative modification with heterostructure construction,element dop-ing and inverse opal structure.The catalyst presented the highest photocatalytic activity and rate con-stant for degradation of typical organic pollutants Rhodamine B(RhB)and was also used for the efficient removal of antibiotics,represented by norfloxacin(NOR),sulfadiazine(SD)and levofloxacin(LVX).Char-acterizations confirmed its increased specific surface area,narrowed bandgap,and enhanced visible light utilization capacity.Further mechanism study including band structure study and electron paramagnetic resonance(EPR)proved the successful construction of Z-scheme heterojunction,which improved photo-generated charge carrier migration and provide sufficient free radicals for the degradation process.The combination of different modifications contributed to the synergetic improvement of removal efficiency towards different organic pollutants.
