摘要
The hydrogen storage capacity of Ti decorated B 2C sheet has been investigated by first-principles plane-wave calculation. It is revealed that a single Ti atom adsorbed on the B 2C sheet can strongly bind up to four hydrogen molecules. The adsorption energy is in the range of -0.36-0.82 eV/H 2, which is suitable for ambient temperature hydrogen storage. Considering the fact that Ti can be loaded on both sides of B 2C sheet, corresponding gravimetric storage capacity of Ti/B 2C system was also calculated and it can reach to about 7.0 wt%, exceeding the minimum requirement of 6.0 wt% for applications.
