AbstractTiO2and spinel Cu1.5Mn1.5O4co-modified hierarchically porous zeolite Beta (Ti/Cu1.5Mn1.5O4-HBeta) with 3D interpenetrating micro-mesoporosity has been synthesized, which showed highly efficient catalytic activity to the soot oxidation in the presence of O2/NO/N2due to the rich moderate intensity acidic sites and chemisorbed oxygen species. In the presence of SO2/O2/NO/N2, the SO2could be preferentially adsorbed on the Ti/Cu1.5Mn1.5O4-HBeta and the resulting sulfates could easily decompose at elevated temperatures, thus leading to significantly improved sulfur-resistance. Furthermore, the excellent water-resistance and cycling stability were achieved on the catalyst Ti/Cu1.5Mn1.5O4-HBeta owing to its crystalline zeolite framework and highly dispersed active components. © The Royal Society of Chemistry 2017.
