Three-dimensionally ordered macroporous manganese-based perovskite catalyst (3DOM AMnO₃, A = Ce, La, Ni) were synthesized by PMMA hard-templating and impregnation method. Physicochemical properties of the samples were characterized by means of various techniques including XRD, BET, SEM, TEM, XPS and H₂-TPR, and their catalytic activities were evaluated by toluene combustion. It was found that the 3DOM AMnO₃ in each of the samples was perovskite in crystal structure, and only the samples possessed a good quality 3DOM architecture with a surface area of 48.8 m²/g. Due to the highest adsorbed oxygen species concentration (O_ads/O_latt = 2.330), the best low-temperature reducibility (The low-temperature reduction peaks of 3DOM CeMnO₃ catalysts occur at 425 °C) and the strong interaction between CeO₂ and MnO_x formed during calcination. The 3DOM CeMnO₃ sample showed lower apparent activation energy (34.51 kJ·mol⁻¹, SV = 15,000 h⁻¹) and the best catalytic activity for toluene combustion, with the reaction temperatures (T50%, and T90%) required for achieving toluene conversions of 50%, and 90% being 100 °C, 172 °C at SV = 15,000 h⁻¹, respectively.

采用PMMA硬模板浸渍法合成了三维有序的大孔锰基钙钛矿型催化剂（3DOM AMnO ₃，A = Ce，La，Ni）。通过包括XRD，BET，SEM，TEM，XPS和H ₂ -TPR在内的各种技术表征样品的理化性质，并通过甲苯燃烧评价其催化活性。发现每个样品中的3DOM AMnO ₃均为晶体结构的钙钛矿，只有样品具有高质量的3DOM结构，表面积为48.8 m ² / g。由于最高的吸附氧种类浓度（O _ads / O _latt = 2.330），最佳的低温还原性（3DOM CeMnO ₃催化剂的低温还原峰出现在425°C），并且在煅烧过程中形成CeO ₂和MnO _x之间的强相互作用。3DOM CeMnO ₃样品表现出较低的表观活化能（34.51 kJ·mol ^-1，SV = 15,000 h ^-1）和最佳的甲苯燃烧催化活性，而获得甲苯所需的反应温度（T50％和T90％） SV = 15,000 h ^-1时，分别为50％和90％的转化率分别为100°C和172°C 。
