1. A sorbent material comprising a nanofiber composite, the nanofiber composite comprising a polymeric material defining a continuous phase and at least one metal organic framework (MOF) material defining a discontinuous phase, wherein the at least one MOF material is dispersed throughout the continuous phase of the polymeric material, and wherein the polymeric material comprises a hydrogel polymer.
 
12. A method of making a sorbent material, comprising:
(i) forming a spinning composition comprising a polymeric material and at least one metal organic framework (MOF) material dispersed throughout the polymeric material; and
(ii) forming one or more nanofiber composites from the spinning solution, the one or more nanofiber composites including the polymeric material defining a continuous phase and the least one MOF material defining a discontinuous phase dispersed throughout the continuous phase of the polymeric material.
