 In this study, researchers developed a new method to create flexible carbon framework electrocatalysts from nanosellulose fibers and carbon nanotubes. This method involves freezing the materials into a desired shape and then assembling them at the interface. The resulting material is both mechanically flexible and highly efficient at catalyzing oxygen reduction reactions. Additionally, they were able to use these materials to build a solid state zinc air battery which offers improved performance over traditional batteries.
