Diffuse Reflectance IR Fourier-Transform (DRIFT) spectroscopy is an increasingly popular technique in catalysis research as it permits in situ observation of the reactor bed in powd. or granular form. However, DRIFTS in its conventional form suffers from t ...
We explored the reactivity of gold on cleaved 2212 BiCaSrCuO by synchrotron-radiation photoemission spectroscopy. We found no evidence for reactivity when the substrate was at room temperature, similar to what has been reported for very low temperatures (2 ...
CO2 methanation over Ru/TiO2 was studied by using a diffuse-reflectance IR cell coupled with a continuous-feed recycle reactor. Metal-adsorbed CO is a major reaction intermediate and at 120 Deg occupies approx. 40% of the available Cu surface, while CH4 fo ...
he electrochemical oxidation of phenol for waste water treatment was studied at a platinum anode. Analysis of reaction intermediates and a carbon balance has shown that the reaction occurs by two parallel pathways; chemical oxidation with electrogenerated ...
The advantage of coupling a diffuse-reflectance infrared cell with a continuous-feed recycle reactor for in situ kinetic and mechanistic studies is illustrated in the study of CO2 methanation over Ru/TiO2. From transient and steady-state experiments, metal ...
Glycoaldehyde phosphate aldomerizes in aq. NaOH to a product mixt. contg. the racemates of two diastereomeric tetrose 2,4-diphosphates and 8 hexose 2,4,5-triphosphates. The aldomerization of glycoaldehyde in the presence of formaldehyde is a variant of the ...
Diffuse-reflectance infrared Fourier transform (DRIFT) spectroscopy has been used to study in situ, the low-temperature (T < 200°C) methanation of CO2 over Ru on TiO2 supports and on Al2O3. For 3.8% Ru/TiO2, the reaction exhibits an activation energy (Ea) ...
On treatment with Bu4N+ F-, cyclopropanecarboxylates I (R = Cl; R1 = Cl, F; R2 = OCMe3) undergo Cl-F exchange via cyclopropene intermediates. As a byproduct, H2C:CMeC.tplbond.CCO2CMe3 (II) is formed. I (R = R1 = Cl, R2 = CO2CMe3), II, and Me2CClC.tplbond.C ...
The electrochem. oxidn. of Mn(II) in H2SO4 (30% wt.) has been studied using cyclic voltammetry. The mechanism was shown to be of the type ECE (Electrochem.-Chem.-Electrochem.). The deposition of MnO2 on the anode can be avoided by inhibiting the chem. reac ...
