A 3D Co-CN framework as a high performance electrocatalyst for the hydrogen evolution reaction

A 3D Co-CN framework was synthesized via a sample annealing route at 600 °C using ZIF-67 as the template. When the 3D framework was applied as a hydrogen evolution cathode, the Co-CN electrode shows exceptionally high catalytic activity and good durability, and it only requires overpotentials of 181...

Description
Summary:A 3D Co-CN framework was synthesized via a sample annealing route at 600 °C using ZIF-67 as the template. When the 3D framework was applied as a hydrogen evolution cathode, the Co-CN electrode shows exceptionally high catalytic activity and good durability, and it only requires overpotentials of 181 mV and 266 mV to afford current densities of 10 mA cm −2 in acid (0.5 M H 2 SO 4 ) and alkaline (0.1 M KOH) electrolytes respectively. A 3D Co-CN framework was synthesized with the Co-CN electrode showing exceptionally high catalytic activity and good durability. Only requiring overpotentials of 181 mV and 266 mV to afford current densities of 10 mA cm −2 in acid and alkaline electrolytes, respectively.
