Pt vs. Au in water-gas shift reaction
This work presents a comparison of the gold- and platinum-based catalysts behavior in the water-gas shift (WGS) reaction. The influence of the support, e.g., its composition and electronic properties, studied in detail by means of UV-Vis spectroscopy, of the metal nature and dispersion and of the st...

| Sumario: | This work presents a comparison of the gold- and platinum-based catalysts behavior in the water-gas shift (WGS) reaction. The influence of the support, e.g., its composition and electronic properties, studied in detail by means of UV-Vis spectroscopy, of the metal nature and dispersion and of the stream composition has been evaluated. The catalytic performance of the samples is directly correlated with the electronic properties modification as a function of metal and/or support. Both metals present high activity in the selected reaction although in a different operation temperature window |
