Carbon aerogels (CAs) supported Pt catalysts were prepared separately by directly loading of Pt on the surface of CAs and simultaneously loading of Pt during the synthesis of CAs respectivelyXRD
TEM
ICP and electrochemical cyclic voltammograms were used to evaluate and comparatively discuss the effects of method of loading on the properties of CAs supported Pt catalystThe results showed that simultaneous loading led to large Pt particle size
poor Pt dispersion and low Pt loading quantity
resulting in poor catalytic performance for methanol oxidationOn the contrary
high performance CAs supported catalyst with well dispersed small Pt particle size could be obtained via direct loading.
