采用Mn-MOF-74模板热裂解法制备了球形介孔MnOx纳米颗粒。MnOx纳米颗粒的形貌继承了Mn-MOF-74模板，并且可以通过改变热解条件来调节MnOx颗粒的晶体结构。这些多孔MnOx纳米颗粒作为低温选择性催化还原（SCR）催化剂进行了测试，并表现出较高的活性。在700℃N-2气氛下制备的样品具有最大的比表面积（89.1 m(2)/g）和最高的deNO(x)活性（98% NO转化率），N-2选择性几乎为100%。(C) 2016 Elsevier B.V.版权所有
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 degrees C under a N-2 atmosphere had the largest specific surface area (89.1 m(2)/g) and the highest deNO(x) activity (98% NO conversion) with a N-2 selectivity of almost 100%.
