英文摘要	Transition metal oxides (TMOs) have been playing an indispensible role in the catalysis of redox reactions. In particular, two dimensional TMOs expose their surface/edge sites to a large extent, which brings unique catalytic features such as greatly enhanced catalytic activities. Here a series of MnO2 nanosheets have been facilely synthesized by a simple redox reaction between KMnO4 and 2-(N-morpholino) ethane sulfonic acid (MES) at room temperature. Among the obtained MnO2 samples, MnO2-48 h showed the highest performance in removing C2H4 resulting from its highest concentration of surface active oxygen species. To further improve the oxidation activity of the catalyst, a small amount of Pt nanoparticles (NPs) was subsequently loaded on MnO2 nanosheets (Pt/MnO2) by a colloidal deposition method. The Pt/MnO2 demonstrated enhanced catalytic performance and maintained complete removal of 20 ppm C2H4 at 50 degrees C for at least 12 h, which can be attributed to the large amount of adsorbed oxygen species and synergetic catalytic effect between Pt and the MnO2 support.
