Alkylthiol surface engineering: an effective strategy toward enhanced electrocatalytic N 2 -to-NH 3 fixation by a CoP nanoarray

Building a hydrophobic self-assembled monolayer of octadecanethiol on a CoP nanoarray on a titanium mesh (C18@CoP/TM) greatly enhances the N 2 reduction activity with an NH 3 yield of 1.44 × 10 −10 mol s −1 cm −2 and a FE of 14.03% in 0.1 M Na 2 SO 4 .
