Abstract:The fixing of N 2 to NH 3 is challenging due to the inertness of the N�N bond. Commercially, ammonia production depends on the energy-consuming Haber-Bosch (HÀ B) process, which emits CO 2 while using fossil fuels as the sources of hydrogen and energy. An alternative method for NH 3 production is the electrochemical nitrogen reduction reaction (NRR) process as it is powered by renewable energy sources. Here, we report a tiara-like nickel-thiolate cluster, [Ni 6 (PET) 12 ] (where, PET = 2-phenylethanethiol)] as… Show more
“…It can be utilised as an electrocatalyst in the eNRR, which shows a FE of 26.5% with an NH 3 production rate of 36 mg h −1 cm −2 at −2.3 V vs. Fc/Fc + in a non-aqueous medium (THF), which is highest among purely Ni-based eNRR catalysts to date. 40,45 The active catalyst is a tricoordinated monomeric Ni…”
