Multi-yolk–shell bismuth@porous carbon as a highly efficient electrocatalyst for artificial N₂fixation under ambient conditions

Abstract

Multi-yolk–shell bismuth@porous carbon catalyst was fabricated by facile synthetic processes. The MB@PC catalyst displays deliver a NH₃yield of 28.63 μg h⁻¹mg⁻¹_cat., a Faraday efficiency of 10.58 % at −0.5 V<italic>versus</italic>RHE under ambient conditions.
