摘要

A 3D Co-CN framework was synthesized via a sample annealing route at 600 degrees 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 H2SO4) and alkaline (0.1 M KOH) electrolytes respectively.
