摘要：
The adsorption of environmental gas molecules, i.e., NH3, NO, and NO2 on the gamma-PC surface has been studied using first-principles calculations. The lowest-energy configurations of these molecules on the gamma-PC surface were found and the adsorption energies were calculated. The NH3, NO, and NO2 molecules were found to be physisorbed on the gamma-PC surface. The analysis of the charge transfer between the molecules and the surface predicted NH3 and NO as donors to gamma-PC, while NO2 acted as an acceptor to gamma-PC. Remarkable changes in the band structure of gamma-PC were found upon the adsorption of NO2 on its surface. In addition, significant modulations in the work function of gamma-PC were observed after the adsorption of NH3 and NO.
