Activation of Semiconductor/Electrocatalyst/Electrolyte Interfaces Through Ligand Engineering for Boosting Photoelectrochemical Water Splitting

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 5, 2025

Abstract The loading of transition‐metal oxyhydroxide (TMOH) on semiconductor (SC) has been recognized as a promising approach for promoting photoelectrochemical (PEC) water splitting. Nonetheless, major challenges such substantial carrier recombination and slow surface oxidation continue to hinder the achievement desirable PEC performance. This study proposes feasible ligand engineering strategy simultaneously boost charge separation catalytic kinetics through coordinating 2‐methylimidazole (2‐MI) within SC/TMOH system. In situ ultraviolet/visible spectroelectrochemistry (UV/vis‐SEC) density functional theory (DFT) calculations show that coordination 2‐MI influences TMOH/electrolyte interfaces, notably enhancing dynamics hole transfer while reducing adsorption oxygen‐containing intermediates. As anticipated, BiVO 4 /FeNiOOH/2‐MI photoanode demonstrates an impressive photocurrent 6.52 mA cm −2 at 1.23 V RHE , featuring excellent photostability low onset potential 0.35 . Additionally, molecule can be employed in development alternative configurations, /FeNiOOH (soak)/2‐MI, improve efficiency. work opens new horizon designing photoanodes efficient stable

Recent Advances of Ruthenium‐Based Electrocatalysts for Industrial Water Electrolyzers

Advanced Sustainable Systems, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract Hydrogen production by electrochemical water splitting is considered to be a key strategic energy technology, and proton exchange membrane electrolyzers (PEMWEs) anion (AEMWEs) are ideal technologies for green hydrogen in recent years. However, PEMWEs AEMWEs lack low‐cost high‐performance acidic oxygen evolution reaction (OER) alkaline (HER) electrocatalysts respectively, limiting their large‐scale development. Recently, ruthenium (Ru)‐based have received lot of attention because activity better than that commercial catalysts price more affordable, showing great potential OER HER. there still obstacles Ru‐based practical applications industrial electrolyzers, regulatory strategies need developed further optimize its performance. Herein, comprehensive review presented concerning it. First, fundamental principles focus the basic content application discussed. Then, summarized, providing detailed analysis elucidate mechanisms, properties, electrolyzers. Finally, outlooks prospects challenges future proposed.

Titanium‐Doped Hematite Homojunction Photoanodes Based on Nanorod/Nanobowl Arrays for Efficient Solar Water Splitting

EcoEnergy, Journal Year: 2025, Volume and Issue: unknown

Published: April 18, 2025

ABSTRACT Hematite is a promising candidate material for photoanodes, but the efficiency of state‐of‐the‐art hematite photoanodes limited by low absorption coefficient, short hole diffusion length, and slow water oxidation kinetics. In this work, high‐efficiency photoanode was designed fabricated introducing titanium‐doped (Ti:Fe 2 O 3 ) homojunction with different doping contents hierarchical nanorod/nanobowl array structure. The homojuction consisted Ti nanorods grown on high nanobowl arrays, leading to formation broad built‐in electric field, significantly enhancing charge separation transfer within bulk. Furthermore, radially inside bowls bowl edges enabled enhanced light through multiple scattering while offering larger electrode–electrolyte contact area providing more reaction sites. Compared Ti:Fe nanorod exhibited an increase in photocurrent density from 1.6 mA cm −2 3.0 at 1.23 V versus RHE, maintaining long‐term stability over 100 h RHE. This study not only achieved high‐performance also provided new perspective design differently desired nanostructures.
