Hydrophobicity Tailoring of Ferric Covalent Organic Framework/MXene Nanosheets for High‐Efficiency Nitrogen Electroreduction to Ammonia

Advanced Science, Journal Year: 2023, Volume and Issue: 10(15)

Published: March 30, 2023

Abstract Electrocatalytic nitrogen reduction reaction (NRR) represents a promising sustainable approach for NH 3 synthesis. However, the poor NRR performance of electrocatalysts is great challenge at this stage, mainly owing to their low activity and competitive hydrogen evolution (HER). Herein, 2D ferric covalent organic framework/MXene (COF‐Fe/MXene) nanosheets with controllable hydrophobic behaviors are successfully prepared via multiple‐in‐one synthetic strategy. The boosting hydrophobicity COF‐Fe/MXene can effectively repel water molecules inhibit HER enhanced performances. By virtue ultrathin nanostructure, well‐defined single Fe sites, enrichment effect, high hydrophobicity, 1H,1H,2H,2H‐perfluorodecanethiol modified hybrid shows yield 41.8 µg h −1 mg cat.
