Co/N-doped carbon nanospheres derived from an adenine-based metal organic framework enabled high-efficiency
Abstract:
Electrocatalytic nitrate (NO3-) reduction provides us a dual-function strategy for N-contaminant removal and value-added ammonia (NH3) synthesis. However, there is still a lack of efficient electrocatalysts for selective NO3- reduction. Herein, we report the development of Co/N-doped carbon nanospheres derived from an adenine-based metal organic framework (Co@NC) as an attractive electrocatalyst for efficient NH3 synthesis through the reduction of NO3-. Such Co@NC manifests a notable faradaic efficiency of 96.5% and a high NH3 yield of up to 758.0 μmol h-1 mgcat.-1 in 0.1 M NO3--containing 0.1 M NaOH. Moreover, it also demonstrates strong electrochemical stability.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...
