Mesoporous carbon (MC) with high mesopore content and narrow pore size distribution was prepared using colloidal silica as hard template and Pluronic F127 triblock copolymer as soft template, respectively. Then highly dispersed Pt catalyst supported on MC was achieved by ethylene glycol (EG) reduction method. Electrooxidation behavior of EG on the Pt/MC catalyst electrode in sulfuric solution was investigated using cyclic voltammogram (CV), chronoamperometry, linear sweeping voltammogram (LSV) and electrochemical impedance spectra (EIS) analysis. The experimental results indicate that the electrocatalytic performance of the Pt/MC catalyst for EG oxidation is much higher than that of Pt/XC72R catalyst. EIS analysis further reveals that the electrooxidation reaction of EG on the Pt/MC catalyst electrode has a lower charge-transfer resistance. The higher electrocatalytic activity of the Pt/MC catalyst may be due to the promotion of the MC support with large pore size and uniform mesoporous structure on electron transfer ansfer and mass transfer.

Key words: mesoporous carbon, dual template method, ethylene glycol, electrocatalytic, charge-transfer resistance
