摘要：

Wormhole-like orthorhombic LaFeO3 catalysts (LFO-1 and LFO-2) were prepared using the KIT-6 and SiO2 nanospheres as template, respectively. LFO-1 showed better catalytic activity with T-50% and T-90% of 155 and 180 degrees C for CO oxidation, and of 200 and 253 degrees C for toluene oxidation at 20000 mL/(g.h). The excellent catalytic performance was associated with its larger surface area (138 m(2)/g), higher adsorbed oxygen concentration, and better low-temperature reducibility as well as a wormhole-like mesoporous structure.
