Abstract
This disclosure provides systems, methods, and apparatus related to catalytic devices. In one aspect, a device includes a substrate, an electrically insulating layer disposed on the substrate, a layer of material disposed on the electrically insulating layer, and a catalyst disposed on the layer of material. The substrate comprises an electrically conductive material. The substrate and the layer of material are electrically coupled to one another and configured to have a voltage applied across them.
Claims20
A device comprising:
- a substrate, the substrate comprising an electrically conductive material;
- an electrically insulating layer disposed on the substrate;
- a layer of material disposed on the electrically insulating layer, the substrate and the layer of the material electrically coupled to one another and configured to have a voltage applied across them;
- and
- a catalyst disposed on the layer of the material, the catalyst comprising a plurality of islands of catalytic material that are each about one layer or a few layers thick, each island of the plurality of islands of the catalytic material having a dimension substantially parallel to a surface of the layer of the material disposed on the electrically insulating layer of about 1 nanometer to 5 nanometers, the catalyst operable to catalyze a chemical reaction.
