Abstract
Section titled āAbstractāThe effect of structure of the titanium substrate on the electrocatalytic activity of boron-dopped diamond film( BDD) electrode was studied with dimethyl phthalate( DMP) as an organic pollutant mode. 3D porous Ti / BDD electrode can provide more reactive sites for the electrochemical reaction and has faster electron transfer rate compared with planar Ti / BDD electrode. The electrooxidation behavior of DMP on BDD electrodes is direct oxidation based on the results of cyclic voltammetry and liner sweep curves and presented pseudo first-order kinetic at low DMP concentration. Meanwhile,the formation of polymer film was observed at high DMP concentration. Due to the high active area,3D porous Ti / BDD electrode revealed superior performance in the direct electrooxidation of DMP. In terms of chemical oxygen demand( COD) and removal rate when employing different concentrations of DMP,the experimental results on planar Ti / BDD and 3D-Ti /BDD electrodes coincided with the theory proposed.
