摘要
钢铁行业的工业固废具有利用率低且存量巨大等特点,不仅占用了广阔的土地资源,且易对生态环境造成破坏、严重污染自然资源。为提高固废资源的附加值与利用率,钢铁工业固废的可用作制备光催化材料用于降解有机污染物、废水处理等领域,经研究表明将高炉渣、钛渣、稀土渣等固废处理或掺杂稀土元素等方法使其生成的钙钛矿相(CaTiO_(3))及复合氧化物(ABO_(3))结构能够有效提高光催化性能,在酸性条件下效果更佳,且为探索其更深层次地应用于光催化领域提供了相关研究思路。
Industrial solid waste from the iron and steel industry is characterized by low utilization rate and huge stockpile,which not only occupies vast land resources,but also easily causes damage to ecological environment and seriously pollutes natural resources.In order to improve the added value and utilization rate of solid waste resources,the solid waste of iron and steel industry can be used to prepare photocatalytic materials for degrading organic pollutants and wastewater treatment,etc.It has been shown that the calcium-titanium oxide(CaTiO_(3))and composite oxide(ABO_(3))structures generated from the treatment of blast furnace slag,titanium slag,rare earth slag and other solid waste or doping with rare earth elements can effectively improve the photocatalytic performance,which is more effective under acidic conditions.It also provides a relevant research idea to explore its deeper application in photocatalysis.
