Pt-Pd bimetallic nanoparticles anchored on uniform mesoporous MnO2 sphere as an advanced nanocatalyst for highly efficient toluene oxidation
文献摘要：
Improving catalytic performance is a yet still challenge in thermal catalytic oxidation.Herein,uniform mesoporous MnO2 nanosphere-supported bimetallic Pt-Pd nanoparticles were successfully fabricated via a SiO2 template strategy for the total catalytic degradation of volatile organic compounds at low temperature.The introduction of mesopores into the MnO2 support induces a large specific surface area and pore size,thus providing numerous accessible active sites and enhanced diffusion properties.Moreover,the addition of a secondary noble metal can adjust the Oads/Olatt molar ratios,resulting in high catalytic activity.Among them,the catalyst having a Pt/Pd molar ratio of 7:3 exhibits optimized catalytic activity at a weight hourly space velocity of 36,000 mL g-1 h-1,reaching 100％toluene oxidation at 175℃with a lower activation energy(57.0 kJ mol-1)than the corresponding monometallic Pt or non-Pt-based catalysts(93.8 kJ mol-1 and 214.2 kJ mol-1).Our findings demonstrate that the uniform mesoporous MnO2 nanosphere-supported bimetallic Pt-Pd nanoparticles catalyst is an effective candidate for application in elimination of toluene.
