Enhanced Electrocatalytic Activity of Pt-M (M= Co, Fe) Chitosan Supported Catalysts for Ethanol Electrooxidation in Fuel Cells [PDF]
Journal of Nanostructures, 2017 Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared.

Electro-oxidation of Ethanol on Carbon Supported PtSn and PtSnNi Catalysts
Bulletin of Chemical Reaction Engineering & Catalysis, 2016 Even though platinum is known as an active electro-catalyst for ethanol oxidation at low temperatures (< 100 oC), choosing the electrode material for ethanol electro-oxidation is a crucial issue.

Ethanol toxicity and oxidative stress [PDF]
Toxicology Letters, 1992 The mechanisms underlying the toxicity of ethanol have been the subject of much study, but are not well understood. Unlike many selective pharmacological agents, ethanol clearly has several major loci of action. One deleterious factor in ethanol metabolism is the potential for generation of excess amounts of free radicals.

International Journal of Electrochemical Science, 2012 This research is aimed to investigate the Pt-free catalysts for alcohol electrooxidation in alkaline media. The results show that Pd is a good electrocatalyst for ethanol and isopropanol oxidation. The E-TEK Pt/C shows a much higher activity for methanol

Stereospecificity of the Oxidation of Ethanol by Catalase
Journal of Biological Chemistry, 1974 Abstract (R)-[1-3H1]ethanol and (S)-[1-3H1]ethanol were oxidized to acetaldehyde using bovine hepatic catalase. The acetaldehyde formed from the S but not the (R)-[1-3H1]ethanol contained tritium. Thus the stereospecificity of catalase for alcohol is the same as that of alcohol dehydrogenase.

Electrocatalytic oxidation of methane to ethanol via NiO/Ni interface [PDF]
, 2020 Electrocatalytic conversion of methane (CH4) to valuable chemicals under mild conditions is an attractive approach that combines the direct utilization of natural gas as a hydrocarbon feedstock and the chemical storage of renewable electricity.

Oxidant anti-oxidant imbalance and effects of ethanol [PDF]
Frontiers in Bioscience, 1999 This article discusses some of the mechanisms through which alcohol, delivered pre- or postnatally, alters the activity of the rodent hypothalamic-pituitary-adrenal (HPA) axis. We show that blockade of prostaglandin synthesis, but not opiate receptors, modestly interfered with the HPA axis to acute alcohol injection.
