Fig. 7: The desorption behavior of carboxyl groups.

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

Fig. 7

In situ FT-IR spectra after the adsorption of propionic acid for 30 min followed by desorption at desorption times of 1, 5, 10, 15, and 20 min (from top to bottom) on 0.9%Pt1+Ptn/Cu-CuZrOx (a), 0.9%Ptn/Cu-CuZrOx (b), 0.9%PtCu-CuZrOx (c), and Cu-CuZrOx (d) with simulated adsorption models displayed in the same color.
