| Abstract: | We studied the co-adsorption of hydrogen molecule and ions (Li,K,Mg,Ca) inside the single-walled carbon nanotubes (SWNTs) by using density-functional theory (DFT).The band structures (BS),density of states (DOS),charge transfer and difference charge density are presented.We discussed the interaction between the ions (Li,K,Mg,Ca) and H 2.Meanwhile,the binding energy indicates that ionization can increase the adsorption energy of H 2 in CNT. |
