Abstract

Using the structure-induced effect of KBH(mim)₃ ligand, four 2-dimensional (2D) boron imidazolate frameworks with identical body framework and different dangling monocarboxylate ligands, have been synthesized. Electrocatalytic results indicate that the surrounding microenvironment regulation could effectively affect the activity and selectivity towards C₂H₄. BIF-151 showed the highest electrocatalytic performances with the Faraday efficiency (FE) of 25.94% for C₂H₄ at −1.4 V vs. RHE.
