Abstract The adsorption behavior of chloroform (CHCl3) molecules on the surface of graphene decorated by Pdn(n=1—3) atoms/clusters was stu-died in this paper by using the first-principles based on density functional theory. It has been found that there exists only physical adsorption between CHCl3 molecules and pristine graphene (PG), and decorating PG with Pd atoms/clusters can improve the adsorption performance of graphene and lead to stable chemical adsorption between CHCl3 and Pdn(n=1—3) decorated graphene (PG-Pdn(n=1—3)). Among the three adsorption systems of PG-Pdn(n=1—3), the calculation of adsorption energy shows that the graphene decorated by the Pd3 cluster has the best adsorption effect on CHCl3. Charge transfer analysis indicates that CHCl3 transfers a large amount of charge to PG-Pd3. The calculation of charge density confirms the formation of stable chemical adsorption between CHCl3 and PG-Pd3. After CHCl3 is adsorbed on the surface of PG-Pd3, the density of states of the p orbital of the Cl atom effectively overlaps with the s orbital of the Pd atom. Frontier orbital analysis also shows a decrease of the energy gap and an increase of the electrical conductivity of PG-Pd3 after CHCl3 adsorption. Therefore, graphene decorated by Pd3 clusters can be used as a sensing material for the detection of chloroform molecules.
