Bifunctional Electrocatalysts: ZIF-8/ZIF-67-Derived Co-N x -Embedded 1D Porous Carbon Nanofibers with Graphitic Carbon-Encased Co Nanoparticles as an Efficient Bifunctional Electrocatalyst (Small 24/2018)

In article number 1800423, Ling Li, Ze Yu, Lin Gu, and co-workers use ZIF-8/ZIF-67 with electrospinning to successfully fabricate Co-Nx-embedded 1D porous carbon nanofibers. The unique 1D structure, such as higher graphitization degree beneficial, hierarchical porosity, and highly dispersed CoNxC active sites, is beneficial for highly efficient electrochemical performance for oxygen reduction and oxygen evolution reactions.
