Fig. 7: FTIR spectra of carbonylation substrates adsorbed in mordenite.
The different collected conditions of FTIR spectra: (i) MeOH adsorption at 363 K, (ii) 0 min and (iii) 30 min co-adsorption MeOH and CO at 363 K, (iv) carbonylation reactions at 473 K and (v) carbonylation reactions at 573 K. a O–H stretching vibrations: 3800–3000 cm−1, b C–H stretching vibrations: 3100–2700 cm−1, c C≡O stretching vibrations: 2300–2000 cm−1, and d carbonyl frequencies: 1800–1350 cm−1.
