Second, the fixation of CO_2 on Ti/nano-TiO_2-Pt(or Sn) electrodes were investigated by controlled-voltage or controlled-current electrolysis in 0.5M KHCO3 solution under room temperature and ambient pressure.

• 铂、锡微粒修饰Ti/nano-TiO_2电极上 CO_2的电化学还原固定。 在0.；5M KHCO3溶液中分别采用控电流、控电位方式进行 CO_2的电解固定，反应在常温、常压下进行，分别以铂、锡修饰纳米TiO_2电极作阴极，研究了 CO_2的电解还原固定。
