- W3145054959 abstract "对1.0mol/LNiSO 4 和0.5mol/LH 3 BO 3 体系,控制电位为-1.25V,沉积60min,制得高择优取向镍电极.该镍电极经X射线衍射测定其织构度TC 220 为92％.采用循环伏安法研究了1mol/LNaOH溶液中高择优取向镍电极上丙醇的电催化氧化机理及活性,结果表明:高择优取向镍电极对正面醇的电催化活性高,对异丙醇的电催化活性小;推导出正丙醇的电氧化动力学方程,运用稳态极化曲线测定了其电氧化过程的动力学参数.Ni(Ⅱ)氧化为Ni(Ⅲ)的反应速度常数K 1 (E)＝5.25×10 －13 exp(0.488FE/RT),Ni(Ⅲ)还原为Ni(Ⅱ)的反应速度常数K -1 (E)＝2.46×10 -4 exp(-0.512FE/RT),Ni(Ⅲ)氧化正丙醇的反应速度常数K 2 ＝5.64×10 －6 L·mol -1 s -1 ." @default.
