以嵌段共聚物 F127为软模板，低分子量酚醛树脂为前驱体，通过溶剂挥发诱导自组装(EISA)方法制得介孔碳(OMC)，经浸渍还原法制备介孔碳负载铂催化剂(Pt/OMC )。采用场发射扫描电镜(FESEM)、X射线能谱(EDS)、透射电镜(TEM)、X射线衍射(XRD)、N2吸附-脱附等温线等对其进行了表征。Pt/OMC对甲醛的催化性能结果表明，反应7h甲醛的去除率可达92.5%，甲醛可矿化为 CO2。还研究了甲醛的降解机理，甲醛首先被氧化成甲酸，然后再矿化为CO2和 H2 O。

The ordered mesoporous carbon was synthesized with triblock copolymer pluronic 127 as the soft tem-plate,phenolic resins with low molecular weight as carbon sources via the evaporation induced self-assembly route.The ordered mesoporous carbon supported platinum (Pt)catalyst (Pt/OMC)was prepared by chemical reduction method,characterized by scanning electron microscope (FESEM),energy dispersive X-ray spectros-copy (EDS),transmission electron microscope (TEM),X-ray diffraction (XRD)and nitrogen adsorption-de-sorption isotherm.The catalytic activity of Pt/OMC on formaldehyde was investigated.It indicated that Pt/OMC had excellent catalytic activity,and the removal rate on formaldehyde was more than 92.5% in 7h.More-over,it could be mineralized to carbon dioxide.High performance liquid chromatography (HPLC)and gas chromatography (GC)were used to investigate the reaction mechanism for degrading formaldehyde,revealing that the formaldehyde was first decomposed into formic acid,then mineralized to carbon dioxide and water.
