摘要:
Adsorption of O-2 on the M doped SiC sheets (M = Fe, Co, Al, Cu, and Zn) have been studied by density functional theory. We found that M-Si doped SiC sheets have the higher structural stability than Mc doped SiC sheets. Compared with pure SiC sheet, M-C doped SiC sheets have the larger adsorption energy to O-2. When O-2 molecule is adsorbed away from and on M site, the most stable adsorption structures are the Co-C and Cu-C doped SiC sheets respectively. Density of state (DOS) of the most stable structures are calculated to investigate the adsorption process. Based on calculated results, the M-C doped SiC sheets are more suitable for adsorption of O-2. (C) 2018 Elsevier B.V. All rights reserved.
