Construction of oxygen-bridged multi-interface sites in nanotubes for high-efficiency electrocatalytic nitrite reduction to ammonia

Abstract

Herein, oxygen-bridged multi-interface sites were constructed, and their catalytic performance for the electrocatalytic reduction of nitrite to ammonia was systematically investigated. The optimized oxygen-bridged multi-interface sites achieved a Faradaic efficiency of 96.4% and an ammonia yield rate of 361.5 μmol h−1 cm−2 at −0.79 V vs. RHE.
