Electrochemical promotion of propane oxidation on Pt deposited on a dense β″-Al(2)O(3) ceramic Ag(+) conductor

A new kind of electrochemical catalyst based on a Pt porous catalyst film deposited on a β″-Al(2)O(3) ceramic Ag(+) conductor was developed and evaluated during propane oxidation. It was observed that, upon anodic polarization, the rate of propane combustion was significantly electropromoted up to 4...

Descripción
Sumario:A new kind of electrochemical catalyst based on a Pt porous catalyst film deposited on a β″-Al(2)O(3) ceramic Ag(+) conductor was developed and evaluated during propane oxidation. It was observed that, upon anodic polarization, the rate of propane combustion was significantly electropromoted up to 400%. Moreover, for the first time, exponential increase of the catalytic rate was evidenced during galvanostatic transient experiment in excellent agreement with EPOC equation.
