ELECTROCATALYST MATERIAL, ESPECIALLY RHODIUM SULPHIDE ELECTROCATALYST MATERIAL, PROCESS FOR PRODUCING IT AND ELECTROCATALYST

摘要

A rhodium sulfide electrocatalyst formed by heating an aqueous solution of rhodium salt until a steady state distribution of isomers is obtained and then sparging hydrogen sulfide into the solution to form the rhodium sulfide and a membrane electrode assembly with the said electrode and a process for electrolyzing hydrochloric acid.
