Further described herein are extensions to the basic concept of LHs as electrode materials, include both new materials for use with LHs and higher order poly-layer hydroxides (PLHs) as well as methods for synthesizing improved LH material such as with conductive supports or through the use of cross-linking. Finally, also described herein are embodiments enabling the use of LHs as flow electrodes as well as the use of 2-d LH materials for surface redox reactions.

Layered hydroxides as anion insertion materials

A foam electrode comprising surface treatment by the steps of: 1) impregnating soft compressible polymeric foams with a conductive coating via sequential infiltration synthesis and 2) functionalizing the chemically altered voids with an ultrathin redox coating to enhance capacitive deionization (CDI). The redox coating will allow treated foam to absorb ions under the application of a bias, and mechanical compression/decompression. The CDI apparatus uses the void volume of the foam in the uncompressed state to flow liquids through it while the compressed state is used to enhance desalination by limiting the diffusion pathways for the ions to find an adsorption surface.

Compressible foam electrode

A method of etching an organic or hybrid inorganic/organic material. The method etches molecular layer deposition coatings. An etching cycle comprises a first half reaction exposing the coating to a precursor. A second half reaction exposes a second precursor, removing or etching a portion of the coating.
