1D Co‐ and N‐Doped Hierarchically Porous Carbon Nanotubes Derived from Bimetallic Metal Organic Framework for Efficient Oxygen and Tri‐iodide Reduction Reactions

Hierarchically porous Co- and N-doped carbon nanotubes are designed as highly efficient electrocatalysts for both oxygen and tri-iodide reduction reactions via a dual-template synthesis approach. Bimetallic Zn/Co-based-zeolitic imidazolate frameworks coated on tellurium nanotubes are pyrolyzed, generating a structure with high surface area, hierarchical pore structure, abundant Co–Nx active sites, and a 1D tubular graphitic carbon framework.
