Abstract
A mixture and method for the storage and delivery of a gas are disclosed herein. In one aspect, there is provided a mixture comprising: an ionic liquid comprising an anion and a cation, at least a portion of the gas that is disposed within and reversibly chemically reacted with the ionic liquid, and optionally an unreacted gas. In another aspect, there is provided a method for delivering a gas from a mixture comprising an ionic liquid and one or more gases comprising: reacting at least a portion of the gas with the ionic liquid to provide the mixture comprising a chemically reacted gas and an ionic liquid and separating the chemically reacted gas from the mixture wherein the chemically reacted gas after the separating step has substantially the same chemical identity as the chemically reacted gas prior to the reacting step.
