摘　　要：The electrochemically assisted photocatalytic degradation of direct sky blue aqueous solution with three dimensional electrodes was studied. The degradation rates as high as 99%, with a high decolorization ratios of 96 8% and TOC concentration reduction of about 80 5% were observed during a period of 30 min in presence of both photocatalyst and filler electrodes. The kinetics of electrochemically assisted photocatalytic degradation of direct sky blue was also investigated.The electrochemically assisted photocatalytic degradation of direct sky blue aqueous solution with three dimensional electrodes was studied.
