We report a supramolecular porous organic cage platform composed of cobalt porphyrins for catalyzing the electrochemical hydrogen evolution reaction (HER) from water at neutral pH. Owing to its permanent porosity, the supramolecular structure yields a catalyst film with a 5-fold increase in the number of electrochemically active cobalt atoms and an improvement in Tafel slope from 170 mV/decade to 119 mV/decade compared to a planar cobalt porphyrin analog, reaching activities over 19,000 turnovers for HER over a 24-hour period with 100% Faradaic efficiency.

Atomically dispersed Ni in β-Mo2C (Ni/β-Mo2C) is designed as an efficient catalyst for the HER at all pH values. The remarkable electrochemical properties of Ni/β-Mo2C are mainly attributed to the synergistic effect between atomically dispersed Ni species and β-Mo2C.
