Enhancing photocatalytic degradation of phenol through nitrogen- and nitrogen/fluorine-codoped Ti-SBA-15

Abstract

F–N/Ti-SBA-15 and N/Ti-SBA-15 were prepared by hydrothermal method using ammonium fluoride and triethylamine as nonmetal dopants, respectively. The structure and surface properties of the as-prepared samples have been characterized by N2 adsorption–desorption isotherms, UV-Vis DRS spectra, FT-IR and XPS. It was found that the doping of non-metals could narrow the band gap of samples without changes in the mesoporous structure properties. The F–N/Ti-SBA-15 was demonstrated as efficient catalyst for photodegradation of phenol both in the UV light and visible light. The formation of surface oxygen vacancies may be responsible for the promotion of nonmetal F–N/Ti-SBA-15 on the photodegradation of phenol.
