摘要:The Haber-Bosch process for the synthesis of ammonia (NH 3 ) not only causes large energy consumption but also leads to CO 2 emissions. Electrocatalytic hydrogenation of N 2 to NH 3 under ambient conditions is a highly desirable alternative method; however, it needs an efficient electrocatalyst. In this study, we report a mesoporous boron nitride (MBN) metal-free electrocatalyst for the N 2 reduction reaction under ambient conditions. Owing to its mesoporous structure, this MBN electrocatalyst can expose more active sites, resulting in an outstanding NH 3 formation rate of 18.2 μg h -1 mg cat. -1 with a faradaic efficiency of 5.5% at -0.7 V vs. reversible hydrogen electrode in 0.1 M Na 2 SO 4 . It also demonstrates strong long-term electrochemical durability. © 2019 The Royal Society of Chemistry.
