Electrolyte-dependent HER activity of mesoporous iron-based ZIF-67 leaf-like nanosheets

Owing to its greater specific surface area and electrical conductivity, mesoporous nature and leaf-like structure, Fe@ZIF-67-2 showed an overpotential of 45 mV and a Tafel slope of 32 mV dec −1 along with a TOF of 129.35 ms −1 in 1 M KOH.
