Abstract Carbon aerogel (CA) as the catalyst support was synthesized via a sol-gel process. Pt/CA catalysts were prepared by intermittent microwave-assisted polyol process. The content of Pt was measured by inductively coupled plasma (ICP). The results of X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements show that the catalyst particles distributed homogeneously. The mean particle size of Pt/CA is about 4 nm. The chemical contents of the catalysts were analyzed using energy diffraction X-ray(EDX)spectroscopy. The electrochemical property of carbon aerogel supported Pt catalyst for methanol oxidation was evaluated by cyclic voltammetry (CV), linear-sweep voltammetry (LSV), and chronoamperometry. The results of electrochemical measurements show that the activity of Pt/CA catalyst is better than that of Pt/C catalyst.
