Co nanoparticle-decorated radix cynanchi daniculati-derived carbon for efficient electrocatalytic nitrite reduction to ammonia†
The electrocatalytic nitrite (NO2−) reduction reaction (NO2−RR) is an eco-friendly and sustainable method to remove NO2− pollution under ambient conditions while producing high value-added ammonia (NH3). However, the conversion of NO2− to NH3 is governed by a complex six-electron transfer mechanism, necessitating the development of catalysts that exhibit high efficiency and selectivity. Herein, we report Co nanoparticle-decorated radix cynanchi paniculati-derived carbon (Co@RCPC) as a highly active electrocatalyst for NO2− to NH3 conversion. Co@RCPC attains an excellent faradaic efficiency of 92.77% and an NH3 yield of 1235.62 μmol h−1 cm−2 in alkaline solution. In addition, it also demonstrates superior stability in recycling stability tests and consecutive long-term electrolysis tests.
