Ultrasmall iridium nanoparticles on graphene for efficient nitrogen reduction reaction

Abstract

The electrochemical N2 fixation using renewable electricity in water provides a renewable route for artificial NH3 synthesis, whereas developing active and selective catalysts is highly necessary for efficient N2 reduction...

FeMo–N nanosheet arrays supported on nickel foam for efficient electrocatalytic N2 reduction to NH3 under ambient conditions

“…S7 (ESI†). As seen, although Fe 1 Mo 1 –N was not so reactive as noble metals, such as Ir 8 and Ru, 9 its optimal NH 3 yield rate is comparable with those of other Mo or Fe metal compound electrocatalysts reported in the previous literature, such as 3R-MoS 2 , 43 FeTe 2 , 44 etc. Though the NH 3 yield rate and FEs of Fe 1 Mo 1 –N were higher than those of 3R-MoS 2 , the reaction potential of 3R-MoS 2 was lower.…”

“…5 To meet this need, various metals have been explored so far for use in electrocatalysts for NRR applications. 6 Although noble metals, such as Au, 7 Ir, 8 Ru, 9 and Pd 10 , are often employed, which show outstanding activity for the NRR, their high cost and scarcity limit their large scale (or industrial) applications. 11,12 As non-precious metal catalysts, on the other hand, Fe and Mo are now the most widely used elements because they are located near the top of the nitrogen binding energy plot.…”
