Nanostructured Catalysts of Methanol Electrooxidation Based on Platinum–Ruthenium–Palladium and Platinum–Ruthenium–Iridium Alloys Derived from Coordination Compounds

Activities of the synthesized trimetallic catalysts PtRuPd/C and PtRuIr/C supported on highly dispersed carbon soot from solutions of coordination compounds of the corresponding metals are studied in the electrooxidation of methanol. According to the data of voltammetry, the Pt 0.43 Ru 0.47 Pd 0.1 /C and Pt 0.44 Ru 0.46 Ir 0.1 /C catalysts are not inferior to the commercial catalyst Pt 0.5 Ru 0.5 /C in specific characteristics, which is consistent with the data of structural studies and the electrochemical and power characteristics of the membrane electrode unit tested in the composition of a single methanol/air fuel cell.
