摘　　要：用稳态恒电流法和断电流技术研究了Co_3O_4对RuO_2-TiO_2(60)/Ti阳极析氯催化活性和欧姆降的影响。适量Co_3O_4可以大大提高RuO_2-TiO_2(60)/Ti阳极的析氯催化活性,明显减小涂层欧姆降。RuO_2(40)-TiO_2(60)/Ti阳极涂层中近65％的RuO_2被Co_3O_4取代后,电极析氯速率不会下降。The effects of Co_3O_4 on the catalytic activity and ohmic drop of RuO_2-TiO_2 (60)/Ti anode for chlorine evolution were studied by steady-state galvanostatic method and current interruption technique, etc. Appropriate amount of Co_3O_4 will greatly enhance the catalytic activity of RuO_2-TiO_2 (60)/Ti anode for chlorine evolution, and reduce the ohmic drop in anodic coating obviously.The chlorine evolution rate will not decrease as ca. 65% precious metallic oxide in the RuO_2(40)-TiO_2 (60)/Ti anodic coating is replaced by Co_3O_4
