Pt nanoparticles deposited on a low-cost, surfacial,
carbonized palygorskite (Pt/C-PLS) prepared by carbonizing
sucrose were evaluated as a methanol oxidation
catalyst for direct methanol fuel cells. Transmission electron
microscopy and Fourier transfrom infrared spectrophotometry
analyses revealed that carbon was formed on the surface
of PLS and that free silica presented in the C-PLS support.
The catalytic activity of methanol oxidation of Pt/C-PLS
was higher than that of Pt/C, and the former catalyst had
better CO tolerance.
