Carbon aerogels (CAs) were prepared by sol‐gel polycondensation of resorcinol and formaldehyde with BET surface area of 616 m 2 g −1 and the average pore size of 9.8 nm. The prepared CAs were used as supports for Pt nanoparticles for methanol oxidation in alkaline media. In comparison with Pt supported on commercial Vulcan XC‐72R carbon (Pt/C) electrocatalysts, Pt supported on CAs (Pt/CAs) electrocatalysts exhibited higher peak current density and more negative onset potential toward methanol oxidation. The effects of different parameters such as NaOH concentration, methanol concentration, and scan rate on the methanol oxidation reaction were investigated in detail. The results showed that the Pt/CAs electrocatalysts had promising application for methanol oxidation in alkaline media.
