In　this　paper,　Cr　oxygenated　species　dispersed　on　Pt　nanowire　assemblies　(PtCrOX　NWs)　were　successfully　prepared　for　the　methanol　oxidation　reaction　by　a　metal　precursor　dilution　strategy.　Notably,　the　PtCrOX　NWs　catalyst　exhibits　excellent　performance　for　electrocatalytic　methanol　oxidation.　Density　functional　theory　results　revealed　that　the　doped　Cr　oxygenated　species,　which　moderated　the　electronic　structure　of　the　Pt　atoms,　can　significantly　decrease　the　free　energy　of　COOH*　formation,　thus　leading　to　superior　methanol　oxidation　performance.
