• Bimetallic Pt-Pd/MCM-41 catalysts were prepared by one-step synthesis method.
• Co-doping of Pt and Pd induced smaller metal size and higher surface Pt(0) content.
• The synergistic effect enhanced oxygen adsorption capacity and the reducibility.
The catalytic performances of Pt-Pd/MCM-41 bimetallic catalysts prepared by one-step synthesis method were investigated for total toluene oxidation in this paper. The experimental results demonstrated that Pt-Pd/MCM-41 was of superior catalytic activity comparing to the monometallic Pt/MCM-41 or Pd/MCM-41 catalysts with the same metallic content, yielding an almost 100% conversion at 180 °C. The following characterization results indicated that the bimetallic catalyst possessed a higher surface Pt(0) content and smaller doped metal size owing to the synergistic effect of the two noble metals, resulting in the improvement of oxygen adsorption capacity and the reducibility.
