Synthesis of highly efficient MnOx catalyst for low-temperature NH3-SCR prepared from Mn-MOF-74 template

Spherical mesoporous MnOx nanoparticles were prepared by the thermolysis of a Mn-MOF-74 template. The morphologies of the MnOx nanoparticles were inherited from the Mn-MOF-74 template and the crystal structures of the MnOx particles could be regulated by changing the thermolysis conditions. These po...

Summary:Spherical mesoporous MnOx nanoparticles were prepared by the thermolysis of a Mn-MOF-74 template. The morphologies of the MnOx nanoparticles were inherited from the Mn-MOF-74 template and the crystal structures of the MnOx particles could be regulated by changing the thermolysis conditions. These porous MnOx nanoparticles were tested as low-temperature selective catalytic reduction (SCR) catalysts and they exhibited high activities. The sample prepared at 700°C under a N2 atmosphere had the largest specific surface area (89.1m2/g) and the highest deNOx activity (98% NO conversion) with a N2 selectivity of almost 100%.
