An investigation on the structures of Sc2B8 clusters by a combination of the genetic algorithm and density functional theory (GA-DFT) and its CO-adsorption

Abstract

The structures of Sc2B8 were investigated by a combination of genetic algorithm (GA) with PBE functional (GA-DFT). Its CO-adsorption were studied by calculations with PBE functional. Many structures include local minimum and global minimum structures were determined. The structural parameters, relative energy, energetic properties, dissociation energy were reported. Results indicated that CO molecule can be adsorbed at many positions of these clusters. Scandium doped boron cluster can be used to produce materials that can treat CO gas by adsorption method.
