接口在之间一二维(2D ) 原子水晶和金属表面能被认为是 nanoreactor,在分子,吸附和催化反应可以发生。在这个工作,我们证明氧置闰和解吸附作用发生在在六角形的硼氮化物(h-BN ) 之间的接口 overlayer 和磅(111 ) 由使用在周围附近的压力 X 光检查光电子出现光谱学(NAP-XPS ) ,光致核裂变电子显微镜学,和低精力的电子显微镜学。而且,在 h-BN 盖子下面的公司氧化被 NAP-XPS 也观察。现在的结果显示在 2D 盖子下面的 nanospace 能被用于表面反应,在小说,表面化学可以被 nanoconfinement 效果导致。
The interface between a two-dimensional (2D) atomic crystal and a metal surface can be regarded as a nanoreactor, in which molecule adsorption and catalytic reactions may occur. In this work, we demonstrate that oxygen intercalation and desorption occur at the interface between hexagonal boron nitride (h-BN) overlayer and Pt(111) surface by using near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS), photoemission electron microscopy, and low-energy electron microscopy. Furthermore, CO oxidation under the h-BN cover was also observed by NAP-XPS. The present results indicate that the nanospace under the 2D cover can be used for surface reactions, in which novel surface chemistry may be induced by the nanoconfinement effect.
