Electrochemical Promotion of Pt Catalyst Electrodes Deposited on Na3Zr2Si2 PO 12 during Ethylene Oxidation

摘要: The electrochemical promotion of Pt catalyst electrode films interfaced with Na 3 Zr 2 Si PO 12 (NASICON), a sodium ion conductor, was investigated during ethylene oxidation. At 430°C, + supply to the under near-stoichiometric ethylene-to-oxygen ratios causes an up tenfold catalytic rate enhancement for coverages 0.03-0.08. behavior system is discussed in terms previous studies using sodium-ion conductors. On basis kinetic data promotional role attributed enhanced oxygen chemisorption on catalyst-electrode surface.
