摘要：

The growth of metal-organic framework (ZIF-67) nanocrystals on nickel foam (NF), followed by carbonization in diluted H-2, leads to a nitrogen-doped carbon-nanotube-grafted cobalt/carbon polyhedra film on NF. The obtained material serves as a highly active binder-free electrocatalyst for both the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), enabling high-performance alkaline (0.1m KOH) water electrolysis with potentials of 1.62 and 0.24V, respectively, at OER and HER current densities of 10mAcm(-2).
