| 摘 要： | 采用浸渍-液相还原法,分别制备了纳米Co、Ni、Mn催化剂,以泡沫镍为集电体,以不同材料作为载体制备电极。采用极化曲线测试了不同催化剂对联氨氧化的催化性能。结果表明,Co和Ni对联氨氧化有明显的催化效果,而Mn基本没有催化效果,Co和Ni相比较,在-0.8 V电位下,Co的电流密度为175 mA/cm2,Ni的达到250 mA/cm2,可见Ni对联氨的氧化反应有较好的催化作用。同时,Vulcan XC-72作为催化剂载体更有助于提高催化剂性能。

| Abstract: | Electrodes were made with foamed nickel as electricity collector,and different materials as carrier of Co,Ni,Mn nanocatalysts that were prepared by the method of impregnation-liquid-phase reduction.The activity for the oxidation of hydrazine of catalysts produced was tested by polarization curve.The results indicated that the effect of Co and Ni was obvious,and it was weak for Mn catalyst.Ni was considered to perform better when compared with Co that the current density of Ni was 250 mA/cm2 while 175 mA/cm2... |
