利用碳粉微电极和显微Raman分子探针技术研究了SOCl~2阴极还原的电催化性能.在八硫杂氢化酞菁的催化作用下, SOCl~2还原过程中的产物硫将进一步还原.碳粉微电极表面沉积物形貌和Raman光谱分析表明硫是引起电极钝化的另一个重要因素,催化剂存在的条件下,硫进一步还原的结果是使碳表面有不同程度的活化,这对提高电池容量和电压有较大影响.

Micro-Raman mol. probe in combination with C powder microelectrodes was successfully used in the electrocatalysis study of SOCl2 reduction The discharge characteristics of Li/SOCl2 cells are usually limited by the large activation/polarization of SOCl2 on C surface. New catalysts octathiahydrophthalocyanine derivatives exhibited superior catalytic activity for reduction of SOCl2 on C surface. The catalytic mechanism and reaction on C cathodes were discussed.
