非贵金属基催化剂用于催化降解有机污染物的研究进展

Research progress of non-noble metal based catalysts for catalytic degradation of organic pollutants

碳达峰、碳中和是一场极其广泛的绿色革命,可以推动经济社会高质量发展,对实现全球绿色转型具有重大意义。当前,随着环境问题的日益加剧,工业废水产生了大量有毒的有机化合物,将这些物质释放到水生环境中会对人类健康造成极大的威胁,因此,对有机污染物的合理处理变得尤为重要,制备具有高催化效率、高循环稳定性、低成本和绿色环保的非贵金属催化剂可以促进绿色可持续发展。阐述了非贵金属基催化剂的研究进展,包括最常用的单/双金属、单/双金属氧化物、层状双金属氢氧化物以及金属基复合催化剂,可以将有机污染物通过绿色环保的方法降解为无毒、无害的物质,符合可持续发展理念。对提高催化降解效果的关键影响因素进行了分析和总结,并对未来研发更加多样化的降解污染物的催化剂指出了方向。

Peak carbon dioxide emissions and carbon neutrality are extremely broad green revolutionans,which can promote high-quality economic and social development and are of great significance to the realization of global green transformation.At present,with the aggravation of environmental problems,industrial waste water generates a large number of toxic organic compounds,releasing of these substances into the aquatic environment will cause a great threat to human health,so the reasonable treatment of organic pollutants becomes particularly important.The preparation of non-noble metal catalysts with high catalytic efficiency,high cycle stability,low cost and green environmental protection can promote green and sustainable development.The research progress of non-noble metal based catalysts was reviewed,including the most commonly used single/bimetal,single/bimetal oxides,layered bimetal hydroxides and metal-based composite catalysts.Organic pollutants can be degraded into nontoxic and harmless substances through green environmental protection methods,in line with the concept of sustainable development.The key influencing factors to improve the catalytic degradation were analyzed and summarized,and the direction of developing more diversified catalysts for pollutant degradation of in the future was pointed out.
