Efficient Electrocatalytic Degradation of 4-Chlorophenol Using a Ti/RuO2–SnO2–TiO2/PbO2–CeO2 Composite Electrode

Electrochemical degradation of methyl orange from wastewater by SS/PbO2‐TiO2‐SnO2 composite electrode with and without UV

“…KCl electrode. The experimental conditions included MO concentration of 50 mg/L, initial pH of 6, current density of 1.75 mA/cm 2 ), 11 and treatment time (10,20,30,40,50, and 60 min) with and without UV irradiation. After treatment, the MO solution were analyzed by UV-visible on the S80 unit (Biochrom, England) to make out the removal efficiency (H) of MO.…”

“…When two semiconductor metal oxides are combined, a Fermi level energy balance will be created due to the electron transfer from TiO 2 to SnO 2 through the particles at the contact boundary 8 . Normally PbO 2 , TiO 2 , and SnO 2 oxides are synthesized into multilayer material to form electrodes such as TiO 2 ‐NTs/SnO 2 ‐Sb/PbO 2 , 9 and Ti/RuO 2 –SnO 2 –TiO 2 /PbO 2 –CeO 2 10 by a combined method of thermal and electro‐decomposites. However, synthesizing composites from two or more different metal oxides using the CV method has not received enough attention.…”

Electrocatalytic Dechlorination of Dichloromethane in Water Using a Heterogenized Molecular Copper Complex

“…Remarkable progress has been made over the past decades with electrocatalytic dehalogenation using a variety of materials. A major portion of dehalogenation electrocatalysts are non-molecular, which can consist of single element or metal alloy electrodes (carbon, − platinum, copper, , palladium, , silver, , and iron , ) and metal oxide materials (SnO 2 , PbO 2 , TiO 2 , RuO 2 , Bi 2 O 3 , and IrO 2 ). − These types of electrodes demonstrate very high efficiency and reactivity, but limitations such as product selectivity and cost of the electrode material are important drawbacks for their further development. In contrast, molecular catalysts are attractive due to (1) facile property tuning from ligand modification, (2) easy selectivity and activity evaluation by incorporation of various types of metal to the catalysts, and (3) low metal content used.…”
