英文摘要	A new synthesis strategy to prepare hierarchical macroporous-mesoporous materials employing poly(ethylene oxide)-poly(phenylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) as a single template and an acid adjusting agent was reported. There is a hierarchical structure including macropores with a size of 50-100 nm and mesopores in the macroporous walls with a size of 3-5 nm. The macroporous walls are composed of rare earth orthoferrite nanopaiticles with a size of 5-10 nm. These hierarchically porous materials show high catalytic activities for the CO + NO reaction, and NO can be fully converted to N-2 at temperatures as low as 350 degrees C, indicating their potential in the catalytic conversion of automotive exhaust gas and other catalysis-related fields. This synthesis strategy is a facile method for the preparation of hierarchical porous materials and may give us a guideline for the synthesis of functional materials with further catalytic applications.; NSFC [21461162001, 21425101, 21321001, 21371011, 21331001]; SCI(E); ARTICLE; yan@pku.edu.cn; 31; 8672-8679; 31
