Development of photoelectrocatalysis techniques for phenol compound degradation under solar light

Dr. Chatchai Ponchio, Thawatchai Chuthamas

Abstract


This research, photoelectrocatalysis (PEC) was developed for phenolic compound degradation using FTO/WO3/BiVO4 electrode. Cumene hydroperoxide (CHP) was selected as the phenolic compound for studying with photoelectrocatic property and the degradation process. The photoelectrocalytic properties were studied by cyclic voltammetry under visible light irradiation. The decreasing of the CHP value was determined by a UV/Vis spectrophotometer. Apply potential and power of light source were optimized for high efficiency and understand the mechanism of the CHP degradation. Moreover, a COD value was studied in order to confirm the conversion of all organic compounds in the system. The optimal conditions found that the PEC technique could eliminate CHP compounds that can be released into bodies of water.  Shows that this technique has developed highly effective for phenolic compound degradation and suitable developed for water treatment systems further.
