Efficient degradation of organic contaminants via a novel iron-based poly(ionic liquid)/polydopamine composite as the heterogeneous Fenton catalyst

Abstract

Iron-based poly(ionic liquid)/polydopamine composite shows excellent degradation performance for organic pollutants, providing a promising route for the design of efficient and stable heterogeneous Fenton catalysts.

Poly(ionic liquid)s: an emerging platform for green chemistry

“…In particular, it allowed for ∼99% malachite green (MG) degradation efficiency with the degradation rate constant up to 1.95 min −1 , which was much higher activity than most of the reported heterogeneous catalysts. 95 Kowsari et al synthesized an optically active polyionic liquid (OAPIL), which was further used to react with silica nanoparticles, yielding product OAPIL/SiO 2 . The final OAPIL/SiO 2 was demonstrated to be an excellent catalyst for the hydrolysis of d , l -phenylglycine methyl ester in water.…”

Advanced research and prospects on polymer ionic liquids: trends, potential and application

“…The composite can be used in a wide pH range and can be recycled seven times without an obvious decrease in catalytic performance, and it can also be used for the decomposition of organic pollutants. The conclusion was drawn 31 that the catalyst exhibits a higher activity than most of the described heterogeneous catalysts.…”
