Ab initio first-principles calculations are carried out to investigate Ti (Sc)-decorated two-dimensional boron-carbon-nitride (BC2N) sheets for their application as hydrogen storage materials. The results show that with four H2 molecules attached to per metal atom the Ti (Sc)-decorated BC2N can store up to 7.6Â wt% (7.8Â wt%) of hydrogen in molecular form. The Kubas interaction and the polarization mechanism lead to the adsorption energy within the range of 0.4-0.56Â eV/H2 (0.13-0.27Â eV/H2), which is suitable for ambient temperature hydrogen storage.
⺠The gravimetric densities of H2 are 7.6 wt% and 7.8 wt%, respectively. ⺠The average adsorption energy of hydrogen molecule is in the range of 0.4-0.56 eV/H2 (0.13-0.27 eV/H2). ⺠It can operate under ambient thermodynamic conditions.
