Resumen:
Two types of catalysts were synthesized and used in the Water Gas Shift Reaction (WGSR): Rh/La2O3 and Rh/La2O3-SiO2. The fresh and used catalysts were characterized through X-ray diffraction (XRD), laser raman spectroscopy (LRS), Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The stability tests performed at 673K (50 h time-on-stream) showed that the Rh/La2O3 slowly deactivated while Rh/La2O3-SiO2 exhibited high stability at least for 50 h on stream. The instrumental techniques offered some clues to explain the possible causes of deactivation of one formulation and the high stability of the other. The latter catalyst was more active than most high-temperature formulations reported in the literature.
