Selective electrochemical nitrogen fixation to ammonia catalyzed by a novel microporous vanadium phosphonate the distal pathway.

Herein, a microporous organic-inorganic hybrid, vanadium phosphonate (VPn) material has been developed. With the combined advantages of the periodic organic-inorganic skeleton, a regular microporous channel with a crystalline pore wall, and good surface area, VPn displays electrocatalytic NRR activity with a selective NH yield (11.84 μg h mg), faradaic efficiency of 26.
