赤泥是拜耳法处理铝土矿的副产物。产生的赤泥的数量在很大程度上取决于所用矿石的类型和处理方法。使用赤泥作为催化剂可以很好地替代现有的工业催化剂。它以三氧化铁（Fe2O3）的形式含铁、高表面积、耐烧结、耐中毒和低成本等特性使其成为许多反应的有吸引力的潜在催化剂。除赤泥外，污水处理厂铁离子污泥的催化性能也得到了研究，主要是由于其氧化铁成分。综述了赤泥作为催化剂的研究进展。考察了催化剂的特性、反应机理和性能，并与氧化铁催化剂和工业催化剂进行了比较。
Red mud is a by-product of bauxite processing through Bayer process. The amount of red mud generated depends largely on the type of ore used and the processing. Use of red mud as a catalyst can be a good alternative to the existing commercial catalysts. Its properties such as iron content in form of ferric oxide (Fe2O3), high surface area, sintering resistance,resistance to poisoning and low cost make it an attractive potential catalyst for many reactions. Besides red mud, ferric ion sludge from wastewater treatment plant has also been studied for its catalytic properties, mainly due to its ferric oxide constituent. This paper reviews the studies on red mud as a catalyst. The catalyst characteristics, reaction mechanisms involved and performance are examined and compared with iron oxide catalyst and commercial catalysts.
