Direct Synthesis of Novel Sponge-Like Porous MnOx Catalysts Derived from Mn-MOFs for High-Efficiently Eliminate o-Dichlorobenzene by Catalytic Combustion

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