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