Abstract: By tailoring the microenvironments of a Ni–N–C catalyst in an acidic MEA electrolyzer, we achieve a CO faradaic efficiency of 95% at 500 mA cm −2 , and the CO 2 loss is reduced by 86% at 300 mA cm −2 at pH 0.5, compared to alkaline CO 2 electrolysis.

Abstract: Five-fold-twinned PtCu nanoframes (NFs) with nanothorns protruding from their edges are synthesized by a facile one-pot method. Compared to commercial Pt/C catalyst, the obtained highly anisotropic five-fold-twinned PtCu NFs show enhanced electrocatalytic performance toward the oxygen reduction reaction and methanol oxidation reaction under alkaline conditions.

Abstract: Reaction temperature is an important parameter to tune the selectivity and activity of electrochemical CO 2 reduction reaction (CO 2 RR) due to different thermodynamics of CO 2 RR and competitive hydrogen evolution reaction (HER). In this work, temperature‐dependent CO 2 RR over Fe‐N‐C and Ni‐N‐C single‐atom catalysts are investigated from 303 to 343 K. Increasing the reaction temperature improves and decreases CO Faradaic efficiency over Fe‐N‐C and Ni‐N‐C catalysts at high overpotentials, respectively. CO current density over Fe‐N‐C catalyst increases with temperature, then gets into a plateau at 323 K, finally reaches the maximum value of 185.8 mA cm −2 at 343 K. While CO current density over Ni‐N‐C catalyst achieves the maximum value of 252.5 mA cm −2 at 323 K, and then drops significantly to 202.9 mA cm −2 at 343 K. Temperature programmed desorption results and density functional theory calculations reveal that the difference of temperature‐dependent variation on CO Faradaic efficiency and current density between Fe‐N‐C and Ni‐N‐C catalysts results from the varied adsorption strength of key reaction intermediates during CO 2 RR.
