Oscillation of the reaction rate, leading to strong, irregular oscillation of the conversion in dependence on the time, and sudden conversion changes occurred in certain temp. and concn. regions in the exptl. study of the catalytic hydrogenation of C2H4 wi ...

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 ...
We identified the nature of the chemical reaction between silver and the cleaved surface of BiCaSrCuO at room temperature as a Bi-Ag reaction with Bi segregation, accompanied by interaction with the Sr atoms. Our synchrotron-radiation photoemission spectra ...
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) ...
A study was made of the effect of the frequency and intensity of the gas oscillations on mass transfer between a gas and a solid surface, under conditions of a linear oscillation direction and a precisely defined surface shape, for the purpose of obtaining ...
CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...
