Abstract:

Using mesoporous SiO2 (SBA-15) as templates and sugar as a carbon precursor, mesoporous carbon (CMK-3) was prepared at different temperatures (600-900 °C). 20%(w) Pt/CMK-3 was then prepared by impregnation reduction with sodium borohydride as a reductant. Cyclic voltammetry (CV) and chronoamperometry were applied to study the catalytic performance and stability toward methanol oxidation for the as-prepared catalyst. CO striping voltammetry was used to determine its anti-poisoning capability toward CO. The results show that the Pt/CMK-3 prepared at 900 °C had the best catalytic performance and stability toward methanol but at a carbonization temperature of 700 °C the Pt catalyst had a lower stripping potential to CO.

Key words: Mesoporous carbon, Methanol, Pt, CO striping
