Abstract
An electrode with a gas diffusion electrode (GDE) layer and a metal-organic framework (MOF) layer. The electrode overcomes mass transport limits by providing a gas diffusion pathway to conductive MOF electrodes. At the same applied potential, this translates to a tenfold improvement in current density (greater than 100 mA cm−2) relative to conventional conductive MOF electrode geometries (less than 1 mA cm−2).
Claims20
An electrode comprising:
- a metal-organic framework layer that forms a gas diffusion electrode layer;
- a hydrophobic layer that consists of a hydrophobic polymer;
- a porous layer that is contiguous with the hydrophobic layer;
- and
- wherein the hydrophobic layer is disposed between, and contiguous with, both the porous layer and the metal-organic framework layer, the metal-organic framework layer having an upper surface that is exposed.
