,Construction and Reactivity of Pt–Ni Catalysts,t the high reduction in temperature can induce more Ni diffuse inward. Upon the reduction at 523 K, the sandwich-like structure with half Ni on the surface and another half Ni inside the nanoparticle can be formed, which shows high CO oxidation reactivity.

Reactivity of Graphene-Confined Pt(111) Surface, K. DFT calculations show the adsorption energy of CO on Pt(111) is decreased by the confinement effect of graphene on top. Furthermore, the dynamic process of CO oxidation is also studied. We find that the graphene wrinkles act as the reaction channels for CO desorption and CO oxidation processes.

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
