Fig. 5: The adsorption and the activation of glycerol and glyceraldehyde.

From: Pt1 enhanced C-H activation synergistic with Ptn catalysis for glycerol cascade oxidation to glyceric acid

Fig. 5

In situ FT-IR spectra of the adsorption of glycerol (a) and glyceraldehyde (b) on 0.9%Pt1+Ptn/Cu-CuZrOx, 0.9%Ptn/Cu-CuZrOx, 0.9%PtCu-CuZrOx, and 0.5%Pt1/Cu-CuZrOx with the simulated adsorption models corresponding to the absorption bands labeled in the same color. Schematic illustrations of glyceraldehyde adsorption in η2-GLAD mode over Pt1 + Ptn sites and Ptn sites are also displayed.
