摘要
A three dimensional electro assisted photocatalytic system was constituted with granular TiO 2 as the photocatalyst. The photocatalytic efficiency of phenol degradation was observed to be 10% and 33.6% , respectively, for common water electrolysis and photocatalysis, while it is increased to 82.8% for the combination of them i.e., the electro assisted photocatalytic system. According to the experimental results, both water electrolysis and anode bias were considered to be responsible for the electro synergism, which may effectively provide active oxygen source and prevent further recombination of photo generated charges.
