From: A strong bimetal-support interaction in ethanol steam reforming
a, b In situ DRIFT spectra, c in situ Raman spectra, d in situ normalized XANES spectra, e in situ Fourier-transform EXAFS spectra at Ni K-edge in R-space, and f Ti K-edge in R-space of CO adsorption and then H2O adsorption on 0.5RhNi/TiO2 catalyst at 400 °C (H2, CO-1, H2O, and CO-2 denote the spectra after successive H2 pretreatment, CO adsorption, H2O adsorption, and CO adsorption again for 20 min on 0.5RhNi/TiO2 catalyst, respectively). g Mass spectral analysis for CO and H2O pulse over 0.5RhNi/TiO2 catalyst and h, i corresponding local magnification regions in g.
