Adsorption of carbon monoxide on Li-ZSM-5: theoretical study of complexation of Li+ cation with two CO molecules.
The Li+ cation complexes with one and two CO molecules have been studied computationally. The calculations reveal the conditions when two CO molecules could bind to one Li+ cation in zeolite Li-ZSM-5. In the absence of dicarbonyls (at low adsorbate coverage or at high temperatures), the IR absorption bands can be assigned only on the basis of the Li+ coordination number to the framework oxygen atoms.
