“…The acetic acid species (v as O–C–O 1545 cm –1 ) also presents a similar trend. The band at 1016 cm –1 together with the characteristic bands at 2938, 2819, and 1337 cm –1 could be assigned as the bidentate methoxy species (v a CH 3 2938 cm –1 , v s CH 3 2819 cm –1 , δCH 3 1337 cm –1 , vC–O 1016 cm –1 ) . Meanwhile, the band located at 1406 cm –1 is attributed to formate; the intensity decreases simultaneously but does not disappear when the temperature rise from 30 to 260 °C.…”

The homologous reactions of methanol and higher alcohols synthesis over Mn promoted Cu−Fe catalysts were investigated by in situ DRIFTS, chemical trapping, H 2 -TPR, CO-TPD, ICP, and XRD. The results showed that the adsorbed CO on iron carbide would contribute to the production of methylene, which increased the probability of the carbon chain growth in the HAS process. Moreover, the results of in situ DRIFTS indicated that homologous reaction of methanol, during which process methanol was oxidized to generate formate species which could be inserted by methylene and resulted in the formation of the acid and anhydride species with more cabon atoms and finally led to the formation of alcohols, existed in the HAS process and will apparently affect the synthesis of higher alcohols. Furthermore, the appropriate addition of Mn could facilitate the carbon chain growth and increase the selectivity to C 2 + alcohols on a Cu−Fe based catalyst.
