Photoemission from solid surfaces can give rich information on chemical states and electronic states of the surfaces, which form the basis for two important surface science techniques: X-ray photoelectron spectroscopy (XPS) and photoemission electron microscopy (PEEM). Nowadays, the applications of the two techniques in surface catalysis recall on development of the instruments operating under near ambient pressure (NAP) conditions. Here, I will introduce our recent NAP-XPS studies in confined catalysis under two-dimensional materials. Furthermore, the development of a new NAP-PEEM technique in Dalian will be introduced. Catalytic reactions such as CO oxidation and Al-ion battery processes under the 2D materials have been dynamically visualized by in-situ NAP-XPS and NAP-PEEM.
