Abstract
In this study, a novel photocatalyst, 4-OMe-2,3,5,6-tetrafluorophenyl acetylide copper (TFPACu), was synthesized by introducing more electron-withdrawing groups (−F) onto the benzene ring of PhC2Cu. The physicochemical properties of TFPACu were investigated using a variety of characterization techniques. The result of Mott-Schottky test suggested that TFPACu is an n-type semiconductor. The active species involved in thephotocatalyticdegradation process were investigated by electron spin resonance (ESR). The results indicate that OH and h+ was the main active species in the photodegradation process. Under natural solar light irradiation, the degradation rate of TC reached 96 % within 30 min. This work will offer a viable idea for the rational design and development of efficient and cost-effective photocatalysts.
