  采用基于密度泛函理论的第一性原理及从头算热力学方法系统地研究了H2S与固体氧化物燃料电池Cu/CeO2阳极的反应,并从热力学上预测了Cu带上S的消除。研究发现Cu/CeO2模型中的氧离子从CeO2表面跃到Cu带的过程是一个放热过程,说明衬底上的氧 离子是非常活泼的。

寻找安全、高效的室温储氢材料是氢能利用的关键,也是当前新能源领域中倍受关注的热点课题.金属有机骨架(MOF)和二维多孔碳结构是极具潜力的纳米多孔储氢材料,它们具有优良的多孔性质和大的比表面积,拥有物理吸氢的先天优势.此外,氢气制成后如何与其他杂质气体分离亦是相当重要的问题,MOF和多孔石墨烯(PG)拥有规则的孔径分布,可作为气体分离的过滤膜.采用第一性原理和巨正则系综蒙特卡罗方法,我们探索了各种修
我们运用非平衡热力学理论描述石墨烯表面氢的吸附、扩散和脱附行为。由于脱附受到限制,原子吸附氢只能在非平衡状态下存在。在室温附近,它们将基本脱附。在石墨烯表面,同时也存在氢的Ortho和Para型二聚物,并导致高温分子脱附。
