氢参与表面上的各种化学过程。虽然氢在其吸附状态下表现出振动和旋转动力学，但在某些情况下，它会扩散到基底中以及表面上，并参与化学反应。此外，氢与表面交换电子，对表面电子结构具有显著影响。在这个个人帐户中，我们回顾了我们最近的研究，氢的表面核动力学，氢跨表面传输，催化氢化/同位素交换反应，以及表面和氢之间的电荷转移，通过使用核反应分析的深度分辨技术和共振增强多光子电离的量子态选择性检测结合表面科学技术。作为未来的前景，我们将利用超低μ自旋旋转光谱直接探测表面的氢电荷态。
Hydrogen is involved in a variety of chemical processes on surfaces. While hydrogen exhibits vibrational and rotational dynamics in its adsorption state, it in some cases undergoes diffusion into the substrate as well as on the surface, and participates in chemical reactions. Furthermore, hydrogen exchanges an electron with surfaces having a significant effect on the surface electronic structure. In this personal account, we review our recent studies on surface nuclear dynamics of hydrogen, hydrogen transport across surfaces, catalytic hydrogenation/isotope exchange reactions, and charge transfer between the surface and hydrogen by using a depth‐resolved technique of nuclear reaction analysis and a quantum‐state‐selective detection of resonance enhanced multiphoton ionization in combination with surface science techniques. As a future prospect, we refer to ultraslowμspin rotation spectroscopy for a direct probe of the hydrogen charge state at surfaces.
