- 摘要：报道了在双槽光电反应器中,紫外光光照二氧化钛阳极时,苯胺在阳极室降解的同时,光生电子在外加电场的作用下移动到石墨阴极上,并还原溶液中的氧生成过氧化氢氧化降解苯胺.光电催化降解污染物时,这种方法同时充分地利用了光生空穴和光生电子,因而是十分有效的.
- Abstract：A new configuration is proposed by using titanium dioxide as a photoanode and graphite as a cathode in two-compartment photoelectrochemical reactor. when the photoanode was illuminated, on its surface the aniline was photooxidized,while the photogenerated electron moved to the cathode where oxygen was reduced to hydrogen peroxide,which also degraded aniline.Thus the method proposed is very effective.
