The kinetics of the reduction reaction at different temperatures was systematically investigated to determine the activation parameters, from which the mechanism of the enhanced catalytic activity is revealed. The RGO-Cu catalysts with excellent catalytic performance and relatively low cost show great ...
Raman spectra of as-made materials were measured by using HORIBA France, LABRAM HR Evolution. In situ Raman spectroscopy analysis was carried out on a confocal Raman spectrometer with a wavelength of 532 nm. Nitrogen temperature programmed desorption (N2-TPD) and carbon dioxide temperature ...
In situ Raman analyses of the soot oxidation reaction over nanostructured ceria-based catalystsTo reduce the emissions of internal combustion engines, ceria-based catalysts have been widely investigated as possible alternatives to the more expensive noble metals. In the present work, a set of four ...

Both Al2O3 and K–Al2O3 were, then, impregnated with aqueous RhCl3·3H2O, dried at 393 K, and in situ reduced in H2 atmosphere to obtain 1 wt.% Rh/Al2O3 and Rh/K–Al2O3 catalysts, respectively. Impacts of the potassium-functionalization on high-temperature behaviour of the Rh ...
