Oscillation of Surface Structure and Reactivity of PtNi Bimetallic Catalysts with Redox Treatments at Variable Temperatures

Over Ni–Pt(111) model catalysts, changes in the surface structure were observed during alternating reduction and oxidation (redox) treatments at variable temperatures (VTs). Pt skin with subsurface Ni and NiO on Pt(111) form upon high-temperature reduction and high-temperature oxidation, respectivel...
