Pd-Pt/Al2O3 Bimetallic Catalysts for the Advanced Oxidation of Reactive Dye Solutions |
| 초록 |
The Pd-Pt/Al2O3 bimetallic catalysts showed high activities toward the wet oxidation of the reactive dyes in the presence of 1% H2 together with excess oxygen. Palladium was believed to act as a promoter to spillover the adsorbed H2 onto the surface of the oxidized Pt surface, and thereby the reducibility of the Pt increased greatly. The organic dye molecule had higher chance to adsorb on the reduced Pt surface under the competition with excess oxygen, which is an essential step for the catalytic wet oxidation. The Pd-Pt/Al2O3 catalysts also produced H2O2 from H2/O2 mixture, and the hydroxyl radical was formed through the subsequent decomposition of H2O2. |
