Enabling electrochemical conversion of N(2)to NH(3)under ambient conditions by a CoP(3)nanoneedle array

The Haber-Bosch process for industrial-scale NH(3)production suffers from hash reaction conditions and serious greenhouse gas emission. Electrochemical N(2)reduction is a sustainable and environmentally-benign alternative for ambient NH(3)synthesis while demands efficient electrocatalysts to drive the N(2)reduction reaction. Herein, we report the ambient electrocatalytic N-2-to-NH(3)conversion with excellent selectivity enabled by a CoP(3)nanoneedle array on carbon cloth (CoP3/CC). When tested in 0.1 M Na2SO4, such CoP3/CC achieves a high faradaic efficiency of 11.94% with an NH(3)yield of 3.61 x 10(-11)mol s(-1)cm(-2)at -0.20 Vvs.the reversible hydrogen electrode. It also demonstrates high durability.
