Metallic Pt as active sites for the water–gas shift reaction on alkali-promoted supported catalysts

The enhancement of the WGS rate by alkali components (Li, Na, and K) was confirmed on Pt/Al2O3. Addition of sodium resulted in the highest promotion. Upon addition of Na, the rate and kinetics of Pt/TiO2 were similar to Pt/Al2O3. Promoted samples showed fully reduced Pt under reaction conditions. Th...
