In　this　work　a　facile　synthesis　for　a　high-performance　PtRuBi/C　catalyst　was　presented　through　a　simple　mixture　of　commercial　PtRu/C　and　Bi(NO　3)3.　Most　of　the　Bimodified　the　PtRu　particle　surface　via　irreversible　adsorption　and　deposition　processes.　X-ray　photoelectron　spectroscopy　analysis　indicated　that　Bi2O3　was　the　main　form　in　the　catalyst　and　that　there　exists　an　interaction　between　Bi　2O3　and　Pt.　The　current　density　of　PtRuBi/C　(1:1:0.2　for　Pt:Ru:Bi)　in　the　cyclic　voltammograms　for　methanol　or　ethanol　oxidation　is　over　2.6　times　higher　than　that　of　PtRu/C.　The　anti-poisoning　ability　of　this　catalyst　was　also　greatly　improved.　The　Bi-containing　catalyst　had　abundant　oxygenated　species　and　facilitated　removal　of　poisonous　intermediate　species.
