Hollow Bi2MoO6 Sphere Effectively Catalyzes the Ambient Electroreduction of N2 to NH3

The industrial production of NH3 mainly uses the HaberBosch process, which consumes plenty of energy and releases large quantities of greenhouse gas. Electrocatalysis provides a promising alternative to realize low-emission and energy-saving pathways to achieve low-carbon and sustainable NH3 production, where a highly identifiable and highly active electrocatalyst is desired for the N-2 reduction reaction (NRR). Herein, our recent experimental observations prove that hollow Bi2MoO6 spheres serve as a highly efficient electrocatalyst for NRR with brilliant selectivity. At -0.6 V versus the reversible hydrogen electrode, the facilitator can acquire values for the FE and production rate as 8.17% and 20.46 mu g h(-1) mg(cat)(-1)., respectively. Meanwhile, hollow Bi2MoO6 spheres also demonstrate excellent electrochemical and structure durability.
