摘要:: 利用磷钼酸化学修饰电极的电催化性能,研究将亚磷酸盐通过电化学合成转变为次磷酸盐.通过循环伏安扫描分析,研究磷钼酸修饰电极的电催化特性.研究结果表明,磷钼酸修饰电极H2PO3-还原为H2PO2-具有明显的催化作用.在研究循环伏安法的基础上,以镍板为阳极,磷钼酸修饰电极为阴极,在一定条件下进行亚磷酸盐电解还原成次磷酸盐的实验.实验结果表明,阴极室亚磷酸盐在一定程度上被转化为次磷酸盐,但是由于受电解电压的制约,转化率较低.

Abstract:: By applying the electro-catalystic performance of molybdophosphate chemically modified electrode,the authors investigated the conversion of phosphite into hypophosphite by electrochemic/ synthesis and cyclic voltammery technology based on electrocatalytic chwacteristic of molybdophosphate chemically modified electrode.Experiments showed remarkable catalytic effect of molybdophosphate modified electrode on the reduction of phosphite into hypophosphite.Based on the study of cyclic voltammery,the experiments of the conversion of phospbite into hypophosphite was conducted under certain condition by taking nickel plate as anode and molybdophosphate modified electrode as cathode.As shown by results,phosphite in cathodal cell was really converted into hypophosphite to a certain extent but its conversion rate was low due to the confinement of decomposition voltage.
