A series of novel lamellar sponge-like MnO_x porous catalysts derived from Mn-MOFs have been prepared via modulator-assisted synthesis method and their catalytic performance has been evaluated for o-dichlorobenzene (o-DCB) catalytic combustion reaction. The catalysts were characterized by BET, XRD, Raman, SEM, TEM, XPS, H₂-TPR, O₂-TPD and other techniques to test the physicochemical properties of the catalysts. The results showed that MnO_x had different morphology and properties. The active oxygen species and large specific surface area of MnO_x played an important role in the catalytic combustion of o-dichlorobenzene. The T₉₀ of the laminar catalyst MnO_x-D, MnO_x-D/M, MnO_x-D/H/M, and MnO_x-D/H was 321, 341, 346, and 355 °C, respectively. MnO_x-D has good catalytic activity for the catalytic combustion of o-DCB, which confirmed that surface lattice oxygen played a crucial role in o-DCB combustion. Additionally, they had good hydrothermal stability, thermal stability and water resistance.

借助调节剂辅助合成方法，制备了一系列由Mn-MOFs衍生的新型层状海绵状MnO _x多孔催化剂，并评价了它们对邻二氯苯（o-DCB）催化燃烧反应的催化性能。通过BET，XRD，拉曼，SEM，TEM，XPS，H ₂ -TPR，O ₂ -TPD和其他技术对催化剂进行表征，以测试催化剂的理化性质。结果表明，MnO _x具有不同的形貌和性能。MnO _x的活性氧种类和大的比表面积在邻二氯苯的催化燃烧中起着重要作用。层状催化剂MnO _x的T ₉₀-D，MnO _x -D / H，MnO _x -D / H / M和MnO _x -D / H分别为321、341、346和355°C。MnO _x -D对o-DCB的催化燃烧具有良好的催化活性，这证明表面晶格氧在o-DCB的燃烧中起着至关重要的作用。另外，它们具有良好的水热稳定性，热稳定性和耐水性。
