Description Electro-Fenton (EF) process has received much attention among the
various advanced oxidation process, due to its higher contaminant removal and
mineralization efficiencies, simplicity in operation, in situ generation of hydrogen
peroxide, etc. Heterogeneous EF process rectifies some of the drawbacks of con-
ventional EF process by using solid catalyst for the generation of reactive hydroxyl
radicals in water medium. The efficiency of various heterogeneous EF catalysts
such as iron oxides, pyrite, iron supported on zeolite, carbon, alginate beads, etc.
was tested by various researchers. All of these catalysts are insoluble in water; and
most of them are stable and reusable in nature. Depending on the iron leaching
characteristics, hydroxyl radicals are generated either in the solution or over the
catalyst surface. Catalysts with higher leaching characteristics exhibit the first
radical generation mechanism, while the stable catalyst with insignificant leaching
exhibits the second radical generation mechanism. Adsorption of the pollutant over
the surface of the catalyst also enhances the pollutant degradation. Overall, hetero-
geneous EF process is very potent, powerful, and useful for the pollutant decon-
tamination from the water medium.
