In Situ Tuning of Catalytic Activity by Thermoelectric Effect for Ethylene Oxidation

American Chemical Society (ACS)
The use of the thermoelectric material BiCuSeO as a support and promoter for catalytic ethylene oxidation is reported here. The catalytic activity of a continuous and noncontinuous Pt catalyst supported on BiCuSeO was observed to be promoted significantly by an in situ generated thermoelectric Seebeck voltage by the temperature difference across the material. It has also been shown that this promotion of catalysis by the thermoelectric effect enabled the material BiCuSeO itself to be highly catalytically active for ethylene oxidation. A linear relationship between the logarithm of the reaction rate and the thermoelectric Seebeck voltage was also observed. The thermoelectric promotion of catalysis is attributed to the change of work function of the catalyst surface, accompanied by a charge transfer from the bulk to the surface that is caused by the thermoelectric effect.

Tuning of Catalytic Activity by Thermoelectric Materials for Carbon Dioxide Hydrogenation

AbstractAn innovative use of a thermoelectric material (BiCuSeO) as a support and promoter of catalysis for CO2 hydrogenation is reported here. It is proposed that the capability of thermoelectric materials to shift the Fermi level and work function of a catalyst lead to an exponential increase of catalytic activity for catalyst particles deposited on its surface. Experimental results show that the CO2 conversion and CO selectivity are increased significantly by a thermoelectric Seebeck voltage. This suggests that the thermoelectric effect can not only increase the reaction rate but also change chemical equilibrium, which leads to the change of thermodynamic equilibrium for the conversion of CO2 in its hydrogenation reactions. It is also shown that this thermoelectric promotion of catalysis enables BiCuSeO oxide itself to have a high catalytic activity for CO2 hydrogenation. The generic nature of the mechanism suggests the possibility that many catalytic chemical reactions can be tuned in situ to achieve much higher reaction rates, or at lower temperatures, or have better desired selectivity through changing the backside temperature of the thermoelectric support.
