摘要
粉煤灰是燃煤电厂产生的大批量固体废弃物,粉煤灰的综合利用不仅限于硅、铝和铁等有价元素的回收,混配水泥混凝土用于铺建道路,粉煤灰还可作为多种催化剂的载体材料用于环境污染物的治理。文章调研了近10 a内粉煤灰作为载体材料负载光催化剂和构建(类)芬顿催化剂的科技文献,详细评述了具有代表性的TiO_(2)光催化剂的粉煤灰负载、利用粉煤灰组分Fe_(2)O_(3)构建(类)芬顿催化体系的研究工作,对各类污染物的降解处理效果给予综合评价,并对未来粉煤灰在催化剂负载应用研究方面提出了展望。
Fly ash is the high yield solid waste produced from the coal-fired power plants.The utilization of fly ash is not limited in the recycling of valuable chemical elements of silicon,aluminum and iron,constructing highways as the ingredient mixed with cement concrete,but supporting various catalysts for treatment of environmental pollutants.In this paper,the literatures published within the recent ten years were summarized to present the investigations and applications of fly ash used as the carriers for photocatalysts and Fenton reagents.The representative works on fly ash-supported TiO_(2)photocatalysis and Fenton reaction assisted with iron oxides from fly ash were reviewed.Besides,the effectiveness of fly ash-based catalysts for contaminant purification was also presented.Moreover,the application of catalysts loading on fly ash-based materials in the future is proposed.
