过硫酸盐非均相催化剂进展

Progress in heterogeneous catalysts for persulfate

综述了目前对活化过硫酸盐的非均相催化剂的研究,并按照零价金属,金属氧化物及金属矿,磁性及负载型复合催化剂,非金属碳纳米管,非金属其它碳材料为主线阐述。介绍了各催化剂的制备方法、催化条件、催化效果、环境影响以及降解污染物的反应机理,并分析了其优势与不足。对非均相催化剂的未来发展方向做了简单展望,扩展过硫酸盐高级氧化的发展前景。

It is reviewed that current researches of heterogeneous catalysts activating persulfate,and in accordance with the zero valent metal,metal oxide and metal ore,magnetic and supported composite catalyst,nonmetallic carbon nanotubes and other carbon nonmetallic materials as the main line. The preparation methods,activation conditions,catalytic effects,environmental impact and reaction mechanism of the catalysts were introduced,and their advantages and disadvantages were analyzed. Finally,the future development of heterogeneous catalysts is briefly looked into,and extend the development prospect of advanced oxidation of sulfate.
