Electrocatalytic Oxidation of Dibenzothiophene and 4,6-Dimethyldibenzothiophene at Gold-Polyaniline (Au-PANI) Composite Electrodes

Recent Advances and Challenges in Developing Technological Methods Assisting Oxidative Desulfurization of Liquid Fuels: A Review

“…Various types of electrolytes, such as acids (H 2 SO 4 /HClO 4 and acetic acid), bases (NaOH ,, and KOH), salts (NaCl and cerium nitrate Ce­(NO 3 ) 3 , ), acid/salt (H 2 SO 4 /chromium sulfate hexahydrate (Cr 2 (SO 4 ) 3 ·6H 2 O)), acetonitrile/water, and ionic liquids, have been used in the ECODS process. The anode catalysts, such as CeO 2 /activated carbon, β-PbO 2 /activated carbon, β-PbO 2 /Ti, AAO-CeO 2 , boron-doped diamond (BDD), graphite, , iron, copper, platinum, and glassy carbon electrodes modified with gold-polyaniline (Au-PANI), and cathode catalysts, such as copper pillar, platinum, graphite, , nickel, stainless steel, etc., have been applied in this process. The anode materials and electrolytes have the most important role in the ECODS.…”
