Abstract The exploiting electrocatalysts for water/seawater electrolysis with remarkable activity and outstanding durability at industrial grade current density remains a huge challenge. Herein, CoMoN x Fe‐doped nanosheet arrays are in‐situ grown on Ni foam, which possess plentiful holes, multilevel heterostructure, lavish Co 5.47 N/MoN@NF Fe‐Co interfaces. They require low overpotentials of 213 296 mV hydrogen evolution reaction (HER) oxygen (OER) under alkaline media to achieve 800 mA cm −2 , respectively, both Tafel slopes (51.1 49.1 dec −1 ) undiminished stability over 80 h. Moreover, the coupled electrolyzer requires voltages 1.735 V yield 500 in water. Notably, they also exhibit exceptional electrocatalytic properties seawater (1.833 V@500 ). experimental studies theoretical calculations verify that Fe doping does reduce energy barrier from OH* O* intermediates during OER process after catalyst reconstruction, non‐metallic N site MoN exhibits lowest overpotential. splendid catalytic performance is attributed optimized local electron configuration porous structure. This discovery provides new design method toward low‐cost excellent catalysts splitting produce hydrogen.

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(11), P. 4779 - 4788

Published: March 7, 2024

Iron phthalocyanine (FePc), characterized by its distinctive Fe–N4 sites, represents a macromolecular catalyst with promising applications in bifunctional oxygen catalysis. However, inherently flat and symmetrical configuration often results relatively weak electrocatalytic performance. In this study, novel approach was employed first anchoring the Co-based zeolitic imidazolate framework onto microsized carbon spheres derived from Zn-based coordination polymer, followed incorporation of dispersed FePc molecules. The resultant catalyst, denoted as FePc-CoNC-CMS, exhibited remarkable reduction reaction/oxygen evolution reaction (ORR/OER) activity an alkaline medium, notably achieving half-wave potential 0.87 V overpotential 313 mV at 10 mA cm–2. Both experimental theoretical investigations revealed that presence on cobalt surface induced significant alterations electron distribution within Fe center, thereby regulating adsorption affinity sites toward oxygen. This structural modification led to outstanding activity. When applied zinc–air batteries, it demonstrated excellent power density 147.6 mW cm–2 satisfactory charge–discharge stability over period 70 h pioneering work integrates metal–organic framework-derived metal–carbon nanomaterials catalysts, offering efficient pathway for multifunctional applications.
