Carbon-composited　3D　network　V-O　Magneli　compounds　V4O7-C　were　prepared　through　the　colloid-impregna-tion-carbonthermic　method.　After　Pt　nanoparticles　loading,　electrocatalysts　for　the　methanol　oxidation　reac-tion　(MOR)　with　different　Pt　contents　Pt/V4O7-C　were　obtained.　The　specific　activity　of　15%　Pt/V4O7-C　was　3847　mA/g,　which　was　2.4　times　that　of　commercial　Pt/C.　After　3000s　durability　tests　the　15%　Pt/V4O7-C　had　a　stability　similar　to　the　Pt/C　(38%　activity　retention),　and　the　20%　Pt/V4O7-C　showed　better　durability　(45%　activity　retention)　than　commercial　materials.　XPS　results　implied　that　a　strong　metal-support　interaction　occurred　between　the　Pt　and　V4O7-C,　which　may　enhance　the　MOR　performance.　Moreover,　a　designed　CO　stripping　experiment　proved　that　V4O7　could　enhance　the　adsorption　of　OH-　and　the　oxidation　reaction　of　intermediates　and　restrain　the　adsorption　of　carbonyl　species　of　MOR.　The　synergistic　effect　between　Pt　and　V4O7-C　was　summarized.　The　interaction　between　Pt　and　Magneli　oxides　may　provide　a　new　idea　for　the　design　of　high　performance　catalytic　materials　for　electrocatalytic　oxidation　in　the　view　of　the　adsorption　of　the　reac-tion　species.
