Abstract:
We have developed a carbon dots/Ag (CDs/Ag) nanocomposite electrocatalyst for electrocatalytic nitrate reduction (NO3RR) to ammonia, achieving a remarkable NH3 faradaic efficiency (FE) of 98.48% and an ammonia yield rate of 198.12 μmol h-1 cm-2 at -0.93 V vs. RHE. Harnessing the CDs' ability to regulate the hydrogen evolution reaction (HER) and the presence of surface-active hydrogen (*H) on CDs/Ag effectively enhance the selectivity of silver nanomaterials toward ammonia synthesis.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
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...
