THE ELECTROCATALYTIC STUDY OF REDUCTION O F THIONYL CHLORIDE

The joint tecnique of micro-Raman molecular probe and microelectrodes of carbon powder has been successfully employed in the eleotrocatalysi s study of SOCl2 reduction. The discharge characteristics of Li/SOCl2 cell are usually limited by the large activation polarization of SOCl2 on surface of carbon. A new type of catalysts, octathia-hydro-phthalo oyanine derivatives, were found to exhibit superior catalytic activity for reduction of SOCl2 on carbon surface. The catalytic mechanism and action on carbon cathodes were dicussed.
