Highly selective and active NO reduction to synthesize NH3 based on graphene-substituted phthalocyanine Cu electrocatalysts†
Abstract
Electrocatalytic reduction of nitric oxide (eNORR) has attracted attention due to its dual function of NO removal and NH3 synthesis. A novel carboxylated-graphene supported phthalocyanine Cu catalyst was synthesized and applied in eNORR, achieving an NH3 yield of 471.9 μmol h−1 cm−2 and Faradaic efficiency of 94.07%, better than most catalysts reported.
