Abstract：

CO　and　H2S　poisoning　of　Pt-based　catalysts　for　hydrogen　oxidation　reaction　(HOR)　stands　as　one　of　the　long-standing　hindrances　to　the　widespread　commercialization　of　proton　exchange　membrane　fuel　cells.　In　this　paper,　a　Ru/Ti4O7　catalyst　is　successfully　synthesized　by　the　microwave-thermal　method.　This　Ru/Ti4O7　catalyst　shows　a　much　higher　noble　metal　mass　activity　than　those　of　commercial　PtRu/C　and　conventional　Ru/C　catalysts.　The　performance　of　the　Ru/Ti4O7　catalyst　under　the　exist　of　CO　or　H2S　shows　insignificant　current　decay,　which　is　far　superior　to　commercial　PtRu/C　and　Pt/C　catalysts.　In　this　Ru/Ti4O7　catalyst,　the　electron　transfer　between　Ru　and　Ti　to　form　d-p　orbital　hybridization　is　considered　to　be　responsible　for　the　favorable　catalytic　HOR　performance　and　the　corresponding　CO　and　H2S　tolerance.　The　interaction　mechanism　formed　by　electron　transfer　may　open　a　promising　way　for　the　subsequent　development　of　anti-poisoning　catalysts　for　PEM　fuel　cell　hydrogen　oxidation　reaction.　©　2024　Hydrogen　Energy　Publications　LLC
