原子层沉积铜修饰MXene在电催化硝酸盐还原制氨及锌-硝酸盐电池中的应用
Application of atomic layer deposition of copper-modified MXene in electrocatalytic nitrate reduction to ammonia and zinc-nitrate batteries
摘要
Abstract
Ammonia(NH3)is an important chemical raw material,but its industrial production mainly relies on the Haber-Bosch process,which has high energy consumption and high carbon emissions.Nitrate is a widely existing water pollutant.Electrocatalytic nitrate reduction to ammonia can not only reduce carbon emissions in ammonia production but also realize the resource utilization of nitrogen-containing wastewater.To optimize electrocatalytic nitrate reduction to ammonia,atomic layer deposition(ALD)technology was used to deposit copper(Cu)layers of different thicknesses on monolayer MXene sheets to prepare Cu-MXene catalysts.The results showed that the Cu-MXene catalyst exhibited excellent catalytic performance,with an ammonia yield of 11.1 mol·gcat.-1·h-1,a Faradaic efficiency of 91.5％.Further application in the assembly of a zinc-nitrate battery gave an open-circuit voltage(OCV)of 1.73 V and a peak power density of 5.5 mW·cm-2.At a current density of 2 mA·cm-2,the zinc-nitrate battery achieved stable cycling operation for 78 hours.关键词
