Conclusions
-
1.
The dehydration of methanol on copper-containing catalysts is realized sequentially with the formation of surface methoxyl, formaldehyde, and formate complexes. The formate type complex is broken down with the evolution of both CO and CO2 into the gas phase.
-
2.
Surface hydroxyl groups participate in the dehydration by reacting with the formaldehyde complex to form formate.
-
3.
A scheme for the synthesis of methanol is discussed in which a significant role is assigned to the surface OH groups which act as catalytically active centers. Carbon monoxide is activated by reacting with these centers to form formate structures which are then sequentially hydrated to methanol.
