Unity of Body and Soul or Mind-Brain-Being?,The work is mainly carried out in ultrahigh vacuum (UHV) systems and fixed-bed microreactor. The UHV systems include an Omicron Multi-NanoProbe System, a DUV-PEEM/LEEM System, and a Leybold XPS System. The fixed-bed microreactor for reactivity test of supported nanoparticles was designed and installed in laboratory.

The subsurface Ni lowers the barrier for CO + O elemental reaction. As thus, the synergetic effect of surface NiO. and subsurface Ni promotes CO oxidation on Pt. The eff

Low-temperature (~423 K) oxidation of Pt-skin structure (Pt/Ni/Pt(111)) induces part of Ni diffuse outward and form NiO on surface. After further oxidation at a higher temperature of 623 K, the catalysts are completely encapsulated by NiO. When the Pt@NiO core–shell stru

Interestingly, CO desorb from the interfacial space between graphene and Pt(111) around room temperature. In contrast, the desorption temperature of CO from bare Pt(111) is ~420
