In this study, the electronic and structural properties of pure and M-doped (M = Zn, Cu, Ni, Co) cadmium oxide nanosheets (CdONS) were investigated using density functional theory. Also the adsorption of benzene and toluene molecules on these nanosheets are studied. The results show that benzene and toluene molecules can be chemisorbed on pure CdONS with adsorption energy
81.79 and
95.46 kJ/mol, respectively. According to obtained results, doping of Zn and Cu atoms in cadmium substituted position don’t have considerable effects on adsorption energy of benzene and toluene (
70 and
85 kJ/mol, respectively), whereas with Ni and Co atoms doping in oxygen substituted position, adsorption energy for benzene and toluene molecules is about
220 and
240 kJ/mol, respectively. So, doped CdONS with Ni and Co atoms can be proposed as proper adsorbents for adsorption of benzene and toluene molecules.
