A method of forming a molecular separation device is provided. The method comprises growing or depositing a silica MFI zeolite coating on a ceramic support. The method further comprises growing a ZIF-8 coating on the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite comprises applying a first reactant fluid including a metal salt and a second reactant fluid including an imidazole reactant to the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite further comprises reacting the first and second reactant fluid with the silica MFI zeolite coating to produce the ZIF-8 coating. In certain implementations, at least a portion of the ZIF-8 coating is interspersed with a portion of the silica MFI coating. A molecular separation device including the ZIF-8 coating and the silica MFI zeolite is also disclosed.

Redox flow battery efficiency and performance may be improved with a high energy density bipyridinium based ionic room-temperature liquid electrolyte. Current electrolytes require solvent to dissolve the redox-active material and a supporting electrolyte to maintain charge balance. A room temperature redox-active electrolyte having intrinsic charge balancing would not need a solvent to form a liquid and would therefore have a higher density of anions and cations involved with charge storage. As such, creating redox-active bipyridinium core ionic materials that are in a liquid form at room temperature or, more particularly, are liquids across the range at which a redox flow battery would operate permit smaller and less costly flow battery design than conventional flow batteries.

Energy dense materials for redox flow batteries

Redox flow battery performance may be improved with a metal containing ionic liquid as a liquid electrolyte. Metal containing ionic liquids are liquids at all temperatures of interest and therefore do not need dilution. As such, voltage separation between the anolyte and catholyte may exceed 0.5 V and therefor rival current state-of-the-art energy storage technologies and with higher voltage separation may attain energy densities above 100 Wh/L.

Energy dense materials for redox flow battery

A redox flow battery is described that does not include an ion exchange resin such as a proton exchange membrane but rather uses a generally stationary separator liquid that separates the anolyte from the catholyte at immiscible liquid-liquid interfaces. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interfaces between the separator liquid and the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. The separator liquid comprises a relatively small total volume of liquid in such a flow battery arrangement as compared to the anolyte and catholyte. Suitable chemical options are described along with system options for utilizing immiscible phases.

A redox flow battery is described that does not include ion-exchange resin such as an expensive proton exchange membrane but rather uses immiscible catholyte and anolyte liquids in contact at a liquid-liquid interface. Solvents and electrochemically active components of the anolyte and catholyte would not cross the liquid-liquid interface between the anolyte and catholyte, but certain ions in each of the anolyte and catholyte would cross the interface during charging and discharging of the redox flow battery. Suitable chemical options are described along with system options for utilizing immiscible phases.

A method for capturing COfrom the ambient air by the use of solid tethered amine adsorbents, where the amine adsorbents are tethered to a substrate selected from the group of silica, metal oxides and polymer resins. The tethered amines are joined to the substrate by covalent bonding, achieved either by the ring-opening polymerization of aziridine on porous and non-porous supports, or by the reaction of mono-, di-, or tri-aminosilanes, with silica or a metal oxide having hydroxyl surface groups. The method includes the adsorption of CO2 from ambient air, the regeneration of the adsorbent at elevated temperatures not above 120&#xb0; C. and the separation of purified CO, followed by recycling of the regenerated tethered adsorbent for further adsorption of COfrom the ambient atmosphere.
