摘　　要：将粉末催化剂负载到成形体上去除室内甲醛等污染物面临着活性位点覆盖率高、过程繁琐和环境污染等问题。通过一步法,在不借助任何粘结剂和表面活性剂的作用下,将锰氧化物(MnO_(x))原位负载到三维多孔的碳聚酯泡棉(CPF)上,得到碳聚氨酯泡棉@锰氧化物(CPF@MnO_(x))。这种复合成型体材料具有优异的甲醛去除性能,在甲醛初始浓度为9.45 cm^(3)/m^(3),空速42000 h^(−1)和相对湿度55%~65%的条件下,其在室温下对于50 L甲醛气体的处理能力达到81.38%。由于其本身的价格低廉、成型性好及优异的除醛特性,该材料在空气净化领域具有广泛的应用潜力。The loading of powder catalysts onto monoliths for the removal of indoor pollutants such as formaldehyde encounters problems such as high active site coverage,cumbersome process and environmental pollution.Carbon polyurethane foam@manganese oxide(CPF@MnO_(x))was obtained by loading manganese oxide(MnO_(x))onto 3D porous carbon polyester foam(CPF)without the aid of any binder or surfactant by one-step in situ loading method.The composite monolithic material has excellent formaldehyde removal performance.Under the conditions of initial formaldehyde concentration of 9.45 cm^(3)/m^(3),air speed of 42000 h^(−1)and relative humidity of 55%~65%,the processing capacity of 50 L formaldehyde gas at room temperature reaches 81.38%.Due to its low price,good formability and excellent formaldehyde removal properties,this material had wide potential for application in the field of air purification.
