Wangyang Ma, Jun Li, Jingzhou Liu and Meng Feng Enhanced Photocatalytic Activity of Thienyl-Porphyrins-TiO2 for Degradation of 4-Nitrophenol Chinese Journal of Chemistry 31
TiO2-based photocatalysts impregnated with Cu(II), Zn(II), Co(II) 5-mono-(2-thienyl)-10,15,20-triphenyl metalloporphyrins respectively, were prepared and characterized. The experiment of photodegradation of 4-nitrophenol in water showed that three photocatalysts all exhibited much higher photoactivity under the visible light irradiation. In addition, the first order rate constants of these photocatalytic reactions were calculated.
