N₂O Decomposition on Singly and Doubly (K and Li)-Doped Co₃O₄ Nanocubes─Establishing Key Factors Governing Redox Behavior of Catalysts.

ABSTRACT: The intimate mechanism of N₂O decomposition on bare and redox-tuned Co₃O₄ nanocubes (achieved by single (Li or K) and double (Li and K) doping) was elucidated. The catalysts synthesized by the hydrothermal method were characterized by X-ray electron absorption fine structure measurements, X-ray diffraction, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, and Kelvin Probe techniques. TPSR and steady-state isothermal catalytic tests reveal that the N₂O turnover frequencies are critically sensitive to the work function of the catalysts, adjusted purposely by doping. For the catalysts obtained by one-pot hydrothermal synthesis, lithiation of the Co₃O₄ nanocubes leads to the formation of {Li'
