Fe-Doped and Carbon Composite Multiphase Hetero-structured Catalysts Based on the Ion-Exchange Strategy for Seawater Electrolysis

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(42), P. 15338 - 15349

Published: Oct. 9, 2023

Seawater electrolysis has attracted much attention as an environmentally friendly technology for hydrogen production. However, the presence of chloride ions, microorganisms, and other impurities in seawater hinders development electrolysis, so it is crucial to construct catalysts with high catalytic activity corrosion resistance. In this work, morphology modulation, Fe doping, carbon composites were simultaneously achieved by ion-exchange method a subsequent selenization process. The prepared Fe-NiMoSe@C bifunctional catalyst hollow nanorod structure exhibited excellent resistance alkaline seawater, requiring only 362 354 mV reach 500 mA cm–2 HER OER, while electrolyzer assembled from required 1.83 V drive 100 cm–2, Faraday efficiency close 100% stability up h. It was shown that doping optimizes electronic environment accelerates reaction kinetics, exposes more active sites, layer can resist making electrolysis.

In Situ Electrodeposition of Ultralow Pt into NiFe-Metal-Organic Framework/Nickel Foam Nanosheet Arrays as a Bifunctional Catalyst for Overall Water Splitting

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(11), P. 5167 - 5174

Published: March 5, 2024

Exploring highly effective bifunctional electrocatalysts with surface structural advantages and synergistic optimization effects among multimetals is greatly important for overall water splitting. Herein, we successfully synthesized Pt-loaded NiFe-metal-organic framework nanosheet arrays grown on nickel foam (Pt–NiFe-MOF/NF) via a facile hydrothermal-electrodeposition process. Benefiting from large exposed specific surface, optimal electrical conductivity efficient metal-support interaction endow Pt–NiFe-MOF/NF catalytic performance, exhibiting small overpotential of 261 mV toward oxygen evolution reaction 125 hydrogen at current density 100 mA cm–2 in alkaline medium. More significantly, the assembled electrolyzer comprising Pt–NiFe-MOF/NF//Pt–NiFe-MOF/NF couple demands low cell voltage 1.45 V to reach 10 cm–2. This work renders viable approach design dual-functional exceptional electrocatalytic activity stability high density, showing great prospect electrolysis commercial application.

Versatile, Stable, and Scalable Gel‐Like Aerophobic Surface System (GLASS) for Hydrogen Production

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(2)

Published: Sept. 29, 2023

Abstract Facile removal of adsorbed gas bubbles from electrode surfaces is crucial to realize efficient and stable energy conversion devices based on electrochemical evolution reactions. Conventional studies bubble have limited applicability scalability due their reliance complex energy/time‐intensive processes. In this study, a simple versatile method reported fabricate large‐area superaerophobic electrodes (up 100 cm 2 ) for diverse reactions using the gel‐like aerophobic surface system (GLASS). GLASS are readily uniformly fabricated by spin‐coating cross‐linking polyallylamine virtually any kinds within 5 min under ambient conditions. Intrinsically hydrophilic gel overlayers with interconnected open pores allow physical separation adhesion catalytic active sites, reducing strength, promoting bubbles. As result, exhibit greatly enhanced efficiency stability reactions, such as hydrogen evolution, hydrazine oxidation, oxygen This study provides deeper insights into understanding effect microenvironment designing practical devices.
