Triggered Directed Electron Redistribution Endowed by Efficient Ohmic Contacts of NiMoN/Ni₃S₂ for Boosting Large Current‐Density Overall Seawater Splitting

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 18, 2024

Abstract The rational construction of interfacial nanostructures metal/semiconductor (MS) contacted electrocatalysts has a significant impact on improving their intrinsic activities. However, MS contacts are often plagued by strong Fermi‐level pinning effect, resulting in the formation Schottky barrier that affects adsorption hydrogen/oxygen intermediates. Herein, an Ohmic contact between metallic Ni 3 S 2 and semiconducting NiMoN is well‐designed, which effectively reduces electron conduction barriers. as‐obtained NiMoN/Ni remarkable bifunctional water electrolysis performance.

Abstract Designing high‐entropy oxyhydroxides (HEOs) electrocatalysts with controlled nanostructures is vital for efficient and stable water‐splitting electrocatalysts. Herein, a novel HEOs material (FeCoNiWCuOOH@Cu) containing five non‐noble metal elements derived by electrodeposition on 3D double‐continuous porous Cu support created. This support, prepared via the liquid dealloying method, offers high specific surface area rapid mass/charge transfer channels. The resulting FeCoNiWCuOOH nanosheets provide dense distribution of active sites. heterostructure between skeletons enhances mass transfer, electronic structure coupling, overall structural stability, leading to excellent activities in oxygen evolution reaction (OER), hydrogen (HER), water splitting reaction. At 10 mA cm −2 , overpotentials OER, HER, 1.0 m KOH solution are 200, 18, 1.40 V, respectively, outperforming most current catalytic performance remains even after operating at 300 100, over 1000 h, correspondingly. has potential applications integrated energy systems.

Dalton Transactions, Journal Year: 2023, Volume and Issue: 53(1), P. 245 - 250

Published: Nov. 23, 2023

The electrochemical CO2 reduction reaction (CO2RR) gives an ideal approach for producing valuable chemicals, offering dual benefits in terms of environmental preservation and carbon recycling. In this work, a strong synergistic effect is constructed by adopting electron-rich graphdiyne (GDY) as the supporting matrix, which significantly stabilizes Au active sites boosts CO2RR process. as-prepared GDY-supported nanoparticles (Au/GDY) exhibit excellent performance, with extremely high faradaic efficiency 94.6% CO well good stability continuous electrolysis 36 hours. superior activity Au/GDY catalyst can be attributed to electronic interaction between GDY substrate, resulting enhanced electron transfer rates stable network catalytically that ultimately promote CO2RR.
