Novel High-Entropy Ceramic/Carbon Composite Materials For The Decomposition Of Organic Pollutants

The Fenton reaction is a commonly used technique for the remediation of industrial pollution, but hydrogen peroxide required in this reaction is highly hazardous and the enormous volume of iron sludge byproducts in-creases significantly the cost of pollution remediation. To address this issue, this study examined the efficacy of the electro-Fenton reaction in degrading pollutants utilizing a complex of graphene and a high-entropy ceramic catalyst, and evaluated the potential of functionalized high-entropy materials for the decomposition of pollut-ants. The degradation of organic water contaminants was investigated utilizing a novel composite of graphene and (AlCrCuFeNi)O high-entropy ceramics, to increase the generation of H2O2 in the electro-Fenton process. Rapid calcination produced five-element (AlCrCuFeNi)O high-entropy ceramics to enhance both the electro-catalytic activity and the stability. Because of the high electro-Fenton efficiency of the high-entropy ceramics, the graphene/(AlCrCuFeNi)O HEC cathode effectively removed 99% methyl orange within 90 min of operation.
