摘要
介孔炭材料与活性炭相比具有较大的孔体积和孔径,高的比表面积以及规则的孔道结构,而介孔炭/氧化硅复合材料兼顾了活性炭与介孔材料的优点,因此在吸附大分子有机污染物方面有很好的应用前景。笔者综述了近年来介孔炭,负载/修饰后的介孔炭,介孔炭/氧化硅复合材料的制备和最新研究进展。在制备方面,根据其制备机理的不同可分为硬模板法和软模板法,制备出有序的介孔炭与介孔炭/氧化硅复合材料。在应用方面,重点介绍了介孔炭材料和介孔炭/氧化硅复合材料对大分子有机污染物的吸附性能。进而对介孔炭/氧化硅复合材料在吸附方面的应用进行了展望。
This paper gives a brief review of the adsorption of organic pollutants on mesoporous carbons and carbon/silica hybrids prepared using soft and hard templating methods. These adsorbents include both pristine and modified ones such as metal-loaded, ammonia-treated, KMnO4-oxidized, CO2-activated, and octyl-grafted carbons and hybrids. The adsorbates cover small-molecule pollutants such as phenol, nitrosamine, nitrobenzene, 4-nitrophenol and 4-chlorophenol, and large-molecule pollutants such as cat- ionic, anionic and non-ionic dyes, bisphenol A, humic acids and rhodamine B. Their adsorption mechanism and kinetics are ana- lyzed. Applications of these mesoporous materials in the adsorption of large-molecule organic pollutants are highlighted.
