Carbonaceous Deposit on Pt particles during Catalytic Wet Oxidation of Phenol |
| 초록 |
Removal of phenol by wet air oxidation was conducted with 1wt% Pt/Al2O3 and 1wt% Pt/CeO2 catalysts. During the reaction carbonaceous materials were formed and deposited on the catalyst surface, and the materials deactivated the catalysts. XPS analysis showed that the carbonaceous materials on the Pt/Al2O3 catalyst were composed of four different morphologies. As the wet oxidation proceeded, C2 and C3 type carbonaceous materials transformed into C4 material. In the Pt/CeO2 catalysts, however, C4 material was not formed through the reaction. The broad profiles of CO2 formation from TPO experiment implied that there were at least two types of carbon deposits burning at different temperatures; one on Pt particles, the other Al2O3 and CeO2. |
