Nanosized TiO2/Ti photoanodes fabricated by metalorganic chemical vapor deposition (MOCVD) under different deposition temperatures were characterized and applied to the photoelectrocatalytic degradation of model pollutant of phenol. The anode prepared at 773K was verified in anatase phase with a size about 60nm and achieved the best photoelectrocatalytic activity, where IPCE could reach as high as 89% and the photoconversion efficiency peaked at 8.4%. The photoelectrocatalytic degradation of phenol was found well fit a pseudo-first-order kinetics, and kept stable performance in five continuous runs, confirming potential application of the electrode prepared by MOCVD for organic pollutants abatement.
