Comparison of 2D and 3D electrochemical oxidation systems for removal of reactive dyes in water

Interfacial synthesis of polyaniline–polypyrrole on electrospun vanadium oxide-embedded TiO2 nanofibers with enhanced photocatalytic performance

“…Nowadays, ∼20% of industrial dyes are discharged into the environment, causing serious environmental pollution and posing a threat to human health. 1,2 Among many technologies for dye removal and treatment, advanced oxidation processes (AOPs) are attracting attention due to their high versatility and efficiency, 3–11 thanks to the powerful oxidizing ability of free radicals, particularly sulfate radicals (SO 4 ˙ − ) generated from peroxymonosulfate (PMS). 4,7,10 Prior to use, PMS needs to be activated by an activating agent (catalyst) which undergoes redox cycles and catalyzes the formation of SO 4 ˙ − .…”
