چکیده مقاله:

In this paper, we have studied the reaction of adsorbed CO and H2 on ZnO surface that have anion vacancy for producing methanol. We suggested a 6 steps mechanism for this reaction.All of calculations were carried out in DFT level of theory and B3LYP method, by the use of LANL2DZ basis set for Zn and 6-31G(d) basis set for another atoms(C,H,O) [1]. In our suggestion mechanism, at first, H adsorbs on the top of oxygen surface and CO molecule adsorbs horizontally on ZnO surface so that the Oxygen atom on CO binds of on Zn atom. Then, one Hydrogen is added to Carbon atom, in each step, and finally the Methoxy component is produced. In the last step, One Hydrogen is added to Oxygen of Methoxy and the Methanol is produced [2].
