摘要: 采用量子化学密度泛函B3LYP方法,对碱金属、碱土金属和过渡金属石墨层间化合物(A-GIC,AE-GIC和T-GIC)进行计算.从原子净电荷、Mulliken重叠布居和轨道电子数等角度讨论了A-GIC和AE-GIC的电子结构与成键特性,初步阐明了结构与性能的关系.根据计算结果,结合热力学分析,讨论实验上尚未知的过渡金属石墨层间化合物合成的可能性.

关键词: 金属石墨层间化合物, B3LYP计算, 电子结构, 热力学分析

Abstract: The B3LYP calculation of DFT method was employed to calculate graphite intercalation compounds of alkali metals, alkaline earth metals and transition metals (A-GIC, AE-GIC and T-GIC). According to the atomic net charges, Mulliken overlap populations and electron numbers of valence obitals, the electronic structures and bonding characters were discussed to clarify the relations between structure and function of A-GIC and AE-GIC. From the B3LYP and the thermodynamic calculated results, the synthesis possibilities of T-GIC (unknown in experiments) were also analysed.

Key words: Graphite intercalation compounds of metals, B3LYP calculation, Electronic structure, Thermodynamic analyse
