Ab initio density functional theory calculations have been performed to investigate the catalytic role of water molecules in the oxidation reaction of ethanol: CH3CH2OH+nH2O→CH3CHO+H2+nH2O (n=0,1,2). The results show that the potential energy barrier for the reaction is 88.0 kcal/mol in ...

Oxidation characteristics of ethanol in the temperature range 200 to 1000°C suitable to its use in automobiles are studied to highlight the role and optimum values of different combustion controlling parameters for its clean combustion. Sensitivity evaluation of different reaction paths has concluded so...
The catalytic activity is determined under conditions of temperature-programmed reaction under atmospheric pressure using a gas mixture (composition, mol %: EtOH, 2; O, 18; He, 80) at a hourly space velocity of the mixture of 3600 h over 0.25–0.5 mm catalyst fraction. The possibility of ...
In this work, the effect of the metal nature on the reaction mechanism of the partial oxidation of ethanol on Pt/CeO2 and Rh/CeO2 catalysts was studied by using diffuse reflectance infrared spectroscopy (DRIFTS) analyses. The results showed that the nature of the metal affected the reaction ...
Hepatic microsomes catalyze the oxidation of methanol, ethanol, propanol and butanol to their respective aldehydes. The reaction requires molecular oxygen and NADPH and is inhibited by CO, sharing thereby properties with other microsomal drug oxidations. This microsomal alcohol oxidizing system increases in...
direct alcohol fuel cells, e.g., alcohol crossover from the anode to the cathode, relatively low activity and complex reaction mechanism of most alcohols, high costs of precious metal catalysts (Pt and Pt/Ru based catalysts), and CO poisoning of Pt catalysts at lower temperature in acidic ...

The MnO2-supported Ni ions could behave as a “single-ion electrocatalyst” toward the ethanol oxidation reaction (EOR) between MnO2 layers in an alkaline solution, leading to much higher utilization efficiency than those in a bulk counterpart. Namely, a mass activity of 4.30 kA g-Ni−1 was...
For these reasons the understanding of each step of ethanol combustion and the development of an accurate oxidation mechanism are of high importance. Earlier studies have identified the first reaction occurring during ethanol combustion thanks to experiments performed in diffusion flames [5], in static...
