Abstract
In this study, we have designed a bench-scale, electro-photocatalytic (EPC) reactor system consisting of a glass beaker, electrolytic cell, aluminium wires and nanoparticles as photocatalysts. Various nanoparticles as types of photocatalysts were utilized for the degradation of methylene blue (MB) by using electro-photocatalysis (EPC) method. The photocatalysts used were pre-synthesized CdS, TiO2 and Ag nanoparticles in the presence of UV-light source (long UV=365 nm) and commercial battery (9 V) to perform electro-photocatalytic (EPC) experiments. For the purpose, different band gap nanomaterials such as CdS quantum dots, TiO2 and Ag nanoparticles were selected to compare their photocatalytic activity. The in-depth comparative study of EPC degradation of methylene blue dye was performed and the results of EPC degradation experiments revealed highest efficiency of 86% in 4 hours. The effect on photo degradation efficiency of these nano-photocatalysts in presence of commercial electronic battery was studied in detail by a high school student under supervision for demonstration of concept that has potential to handle water pollution.
