Co3O4/石墨炔异质界面用于高效硝酸根制氨
A Co3O4/graphdiyne heterointerface for efficient ammonia production from nitrates
摘要
Abstract
The nitrate reduction reaction(NtRR)has been demonstrated to be a promising way for obtaining ammonia(NH3)by converting NO3 to NH3.Here we report the controlled synthesis of cobalt tetroxide/graphdiyne hetero structured nanowires(Co3O4/GDY NWs)by a simple two-step process including the synthesis of Co3O4 NWs and the following growth of GDY using hex-aethynylbenzene as the precursor at 110 ℃ for 10 h.Detailed scanning electron microscopy,high resolution transmission electron microscopy,X-ray photoelectron spectroscopy,and Raman characterization confirmed the synthesis of a Co3O4/GDY heterointerface with the formation of sp-C-Co bonds at the interface and incomplete charge transfer between GDY and Co,which provide a con-tinuous supply of electrons for the catalytic reaction and ensure a rapid NtRR.Because of these advantages,Co3O4/GDY NWs had an excellent NtRR performance with a high NH3 yield rate(YNH3)of 0.78 mmol h-1 cm-2 and a Faraday efficiency(FE)of 92.45％at-1.05 V(vs.RHE).This work provides a general approach for synthesizing heterostructures that can drive high-performance ammo-nia production from wastewater under ambient conditions.关键词
