摘要

利用第一性原理计算

发现Ca原子修饰的g-C

(Ca-C

)具有高的储氢能力。H与Ca-C

之间增强的吸附能主要归功于H-1s和Ca-1s轨道之间较强的化学吸附以及H-1s和Ca-3d轨道之间的杂化。在外加电场下

Ca与g-C

之间的极化具有良好的可调特性

这对于H的吸附和释放具有重要的作用。该理论计算结果能够为提高金属原子修饰的g-C

的储氢能力开辟一条可行之路。

Abstract

The Ca atom decorated g-C

(Ca-C

) is demonstrated to exhibit a high capacity to store hydrogen

by using the first-principles calculations. The enhanced adsorption energy of H to Ca-C

is mainly attributed to the strong chemical adsorption between H-1s and Ca-1s orbitals and the hybridization of H-1s and Ca-3d orbitals. The polarization between Ca and C

exhibits good modulation under the external electric field

which plays an important role in H adsorption and release. Our theoretical results may provide a practical route to improving the hydrogen storage of g-C

by suitable metal atoms decorating.
