Effect of SMSI (strong metal–support interaction) behaviour on CO–H2reaction over supported Rh catalysts

Abstract
The catalytic activity and selectivity in the CO–H2 reaction over supported Rh catalysts were investigated by changing reduction temperatures, supports, and doping alkali metal cations; the reduction at 723 K of TiO2-supported catalysts decreased not only the amounts of hydrogen adsorption but also the CO conversion.
