MOFs-derived copper sulfides embedded within porous carbon octahedra for electrochemical capacitor applications

A novel, efficient and green MOFs-templated sulfidation route has been developed to synthesize Cu1.96S-C hybrid composites, in which ultrafine Cu1.96S nanoparticles are embedded uniformly within porous carbon octahedra. The as-synthesized composites exhibit high specific capacitance and good cycling performance in supercapacitors.
