Popis: This work presents results for the adsorption of the formaldehyde molecule on one Ti-graphene layer formed by 32 carbon atoms. Calculations are done under the DFT (density functional theory) scope as implemented in Quantum espresso computer code. After the equilibrium Ti position above a pristine graphene layer has been obtained, it is added the CH2O molecule to obtain the equilibrium configuration of the entire system. Previously also the equilibrium configuration of the formaldehyde molecule and the graphene layer was obtained. Ti atom makes bonds with both, carbon and oxygen atom of the formaldehyde molecule. Adsorption of CH2O molecule above graphene and Ti-graphene with one and two carbon vacancies is discussed.
