The oxidation of copper catalysts during ethylene epoxidation.
The oxidation of copper catalysts during ethylene epoxidation was characterized using in situ photoemission spectroscopy and electron microscopy. Gas chromatography, proton-transfer reaction mass spectrometry and electron-ionization mass spectrometry were used to characterize the catalytic properties of the oxidized copper. We find that copper corrodes during epoxidation in a 1 : 1 mixture of o...
متن کاملAg-Cu catalysts for ethylene epoxidation: selectivity and activity descriptors.
Ag-Cu alloy catalysts for ethylene epoxidation have been shown to yield higher selectivity towards ethylene oxide compared to pure Ag, the unique catalyst employed in the industrial process. Previous studies showed that under oxidizing conditions Cu forms oxide layers on top of Ag. Using first-principles atomistic simulations based on density functional theory, we investigate the reaction mecha...
متن کاملCharacteristics of Polyaniline Cobalt Supported Catalysts for Epoxidation Reactions
A study of polyaniline (PANI) doping with various cobalt compounds, that is, cobalt(II) chloride, cobalt(II) acetate, and cobalt(II) salen, is presented. The catalysts were prepared by depositing cobalt compounds onto the polymer surface. PANI powders containing cobalt ions were obtained by one- or two-step method suspending PANI in the following acetonitrile/acetic acid solution or acetonitril...
متن کاملElectrode and pH effects on electrochemical reactions during ohmic heating
Undesirable electrochemical phenomena at electrode|solution interfaces during ohmic heating can be avoided or effectively inhibited by choosing an appropriate electrode material. We attempted to understand the electrochemical behavior of four types of electrode materials: titanium, stainless steel, platinized-titanium, and graphite at pH 3.5, 5.0, and 6.5. The electrodes were examined comparati...
متن کاملTowards an Improved Understanding of Electrochemical Oxygen Exchange Reactions on Mixed Conducting Oxides
In solid oxide fuel cells or electrolysis cells with ionic and electronic conducting electrodes, the electrochemical reactions take place at the gas/solid interface of the mixed conducting electrode. This is in contrast to the situation met in aqueous electrolytes, where the reactions occur at the electrode/electrolyte interface. Thus, modified concepts are required to describe the reaction rat...
