000156627 5203_ $$aSupported precious metal catalysts, containing either mono or bimetallic Au and Pt nanoparticles, anchored on a hierarchical porous UVM‐7 silica structure, were prepared and evaluated for the removal of volatile organic pollutants by oxidation. The catalysts were investigated for the simultaneous total oxidation of three model compounds: propene, toluene, and CO, commonly associated with “cold start pollutants” in automotive exhausts. Only Au showed low catalytic activity, while Pt nanoparticles were active, with a greater concentration of accessible Pt nanoparticles corresponding with increased catalytic activity. Interestingly, having both metals present on the same catalyst together was preferential for producing higher activity in the total oxidation of CO, propene, and toluene. The loadings of Pt nanoparticles on the catalyst surface, as well as the synthesis method, were important controlling factors. The order of metal loading deposition was influential, depositing Au and Pt sequentially resulted in surface enrichment of the latter deposited metal, leading to enhanced catalytic performance. When Au and Pt were loaded simultaneously, alloy formation occurred, and the surface Pt enrichment was more moderate, but still maintaining better catalytic performance compared with the pure Pt catalyst.
