Electrochemical behavior and electrocatalytic reduction of the Keggin-type transition metal substitute tungstoborate anions
【摘要】 采用循环伏安法,研究了Keggin结构过渡金属取代硼钨酸盐K7[MBW11(H2O)O39].H2O(简写为MBW11,M=Cu,Co,Ni)的电化学性质及电催化活性.结果表明,CuBW11在水溶液中表现出较为特殊的电化学性质,MBW11(M=Cu,Co,Ni)对亚硝酸根及碘酸根离子的还原反应具有较好的催化作用,取代金属对该体系的电催化活性有很大影响.
【Abstract】 The Electrochemical behavior and the catalytic activities to the reduction of K7[MBW11(H2O)O39]·H2O(MBW11,M=Cu,Co,Ni) has been studied using cyclic voltammetry.The results indicate that CuBW11 exhibits especial electrochemical properties in aqueous solution.The catalytic reactions to reduction of the NO2-and IO3-have been investigated.The substitute metal has a great affect on the electrocatalytic activities in the system.
