【摘要】 利用单一方式去除甲醛效果差，采用物理吸附与催化相结合的方式，可起到优势互补的效果。以硅烷偶联剂（KH550）改性的纳米埃洛石（HNTs）为载体，MnO₂、CuO和CeO₂为催化剂制备了一种用于去除室内甲醛的埃洛石-金属氧化物复合材料。结果表明：Cu-Mn-Ce已负载至纳米埃洛石中；且纳米埃洛石的大孔径和Cu-Mn-Ce的高比表面积为复合材料提供了更利于吸附甲醛的孔结构；此外，Cu-Mn-Ce的负载为复合材料提供了可将甲醛催化转化成CO₂和H₂O的活性氧，经过24h后，复合材料在室温下的甲醛去除率为57.4%。因此，该方法制备的复合材料在室内除醛领域具有一定的研究潜能。更多还原

【Abstract】 The use of a single approach to remove formaldehyde is ineffective, and the use of a combination of physical adsorption and catalysis can provide complementary advantages.A nano halloysite-metal oxide composite for indoor formaldehyde removal was prepared using silane coupling agent（KH550）-modified nano halloysite（HNTs） as the carrier and MnO₂,CuO,CeO₂ as the catalysts.The results showed that Cu-Mn-Ce had been successfully loaded into nano halloysite, and the large pore size of nano halloysite and the high specific surface area of Cu-Mn-Ce provided the composite with a pore structure more conducive to the adsorption of formaldehyde.Moreover, the loading of Cu-Mn-Ce provided the composite with active oxygen that could catalytically convert formaldehyde into CO₂ and H₂O.After 24 hours at room-temperature, the formaldehyde removal rate was 57.4%.Therefore, the composite prepared by this method had certain research potential in the field of indoor formaldehyde removal.更多还原
