Аннотация

A new approach for preparing a PtO_x/CeO₂ catalyst for low-temperature CO oxidation has been developed. The approach includes; i) preparation of a CeO₂ support through the controllable thermal decomposition of Ce(NO₃)₃ ⋅ 6H₂O, and then ii) deposition of polynuclear platinum nitrato complexes ([H₃O⊂18-crown-6]₂[Pt₂(μ²-OH)₂(NO₃)₈][Pt₄(μ³-OH)₂(μ²-OH)₄(NO₃)₁₀]) on the CeO₂ support. The NO₃ ⁻-rich ceria support produced at the onset temperature of Ce(NO₃)₃ -> CeO₂ transformation (220 °C) yields the “PtO_x/CeO₂-220” catalyst that shows intriguingly high activity in CO oxidation, at room temperature and below. To understand the nature of the low-temperature catalytic activity, prepared catalysts have been studied using X-ray photoelectron spectroscopy (XPS), Raman and operando X-ray absorption fine structure spectroscopy (XAFS) and transmission electron microscopy (TEM).
