| A novel Pt supported carbon catalyst (Pt/C) was prepared by carbonization of an anion exchange resin exchanged by [PtCl6]2- and applied to the catalytic combustion of toluene as a model compound of volatile organic compound (VOC). The catalyst prepared contained as large as 30 wt% of Pt in highly dispersed state. Hydrothermal activation at 350 ¢ªC or 400 ¢ªC was performed to develop the pore structure of the catalyst. The BET surface area of the catalyst was increased fourfold and pores of 10 nm or larger and 1 to 2 nm in diameter were greatly developed by the hydrothermal activation at 400 ¢ªC without significantly changing the size of Pt particles. The activity of prepared Pt/C catalyst was very high for toluene combustion and the toluene conversion on hydrothermally activated Pt/C catalyst was as high as 0.9 at 150 ¢ªC and reached 0.3 even at as low as 130 ¢ªC. |
