Abstract:
NEMCA is a phenomenon whereby a metal catalyst deposited on an ionicallyconducting
support shows increased catalytic activity upon application of electrical potential.
Conventional studies of this phenomenon require a large amount of the precursor of the metal
catalyst in the form of paste. Therefore, this deposition method is impractical for commercial
implementation. This work aims to study NEMCA of propane oxidation at Pt deposited on
YSZ (yttria-stabilized zirconia) disks via strong electrostatic adsorption (SEA), which allows
Pt to form finely dispersed nanoparticles. SEA is a special case of wet impregnation by which
the pH of the precursor solution is set to the pH that yields the strongest electrostatic
interaction between the metal ions in solutions and the support. The optimal conditions for
SEA were obtained by varying the pH of the precursor solutions and the metal concentrations
(50-600 ppm.). The point of zero charge (PZC) of YSZ was found to be at pH 5 and the
maximum adsorption occurred at pH 3-4.5, i.e. below the PZC. NEMCA of propane
oxidation at this supported catalyst was studied under an excess of oxygen at 200-480 °C.
Changes in the reaction rates after electrical potentials at 5V were applied were observed. A
high faradaic efficiency of catalytic 2×105 at 200 °C was achieved but decreased as the
temperature increased. The NEMCA effect could be exploited to enhance oxidation rates of
unburnt fuels in catalytic converters, reducing the amount of catalysts required.
