Abstract

Abstract Electrochemical nitrite reduction reaction (NO 2 RR) is considered a sustainable ammonia (NH 3 ) synthesis strategy. However, there are still significant challenges in designing efficient NO 2 RR catalysts. Here, carbon nanotube (CNT)‐encapsulated Ni nanoparticles (NPs) loaded on MXene‐derived TiN (Ni@TiN/CNT) heterostructure is constructed by combining molten salt etching strategy and chemical vapor deposition. Ni@TiN/CNT exhibits an excellent NH 3 yield rate (15.6 mg h −1 mg cat. −1 ), Faradaic efficiency (95.6%), and record cycle stability (NO 2 RR performance is virtually unattenuated after 60 cycles) at −0.7 V versus reversible hydrogen electrode (versus RHE). In addition, the Zn‐nitrite battery…
