Hollow Bi₂MoO₆ Sphere Effectively Catalyzes the Ambient Electroreduction of N₂ to NH₃
2019
The industrial production of NH₃ mainly uses the Haber–Bosch 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 N₂ 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 μg h–¹ mg–¹cₐₜ., respectively. Meanwhile, hollow Bi₂MoO₆ spheres also demonstrate excellent electrochemical and structure durability.
