The surface chemistry of supported ruthenium on high surface area (>50 m 2 g −1 ) rare earth oxides (La, Ce, Pr, Tb, Ho, and Yb) has been studied by temperature-programmed reduction, temperature-programmed oxidation, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and hydrogen chemisorption. Reduction of carbonyl ligands and surface carbonate by H ...
The surface chemistry of supported chromium oxide on lanthanum carbonate has been studied by TPD, FTIR, XPS, and electrophoretic measurement techniques. The active center for the oxidative dehydrogenation of isobutane to isobutylene was identified as a chromate species bound to the surface of lanthanum carbonate. This species was formed as a result of interaction between chromium oxide and lanthanum...
