Tailoring p‐Orbital Electron Delocalization Induced by Sulfur Defect Engineering for Enhancing Photoelectrochemical Water Splitting Performance

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

Published: March 4, 2025

Abstract Indium sulfide (In 2 S 3 ) as water splitting photocatalyst has been broadly investigated due to its narrow bandgap (2.0–2.3 eV) and optimized opto‐electronic properties. However, In still suffers from a rapid photogenerated charge carrier recombination rate. addition, the main group metals (such In) lack active d ‐orbital electrons for catalysis, thus limits activation of intermediates during catalytic reaction. Herein, overcome above limitations , /TiO heterojunction with sulfur defects are constructed by temperature control strategy. The vacancy (Sv) can induce electron density transformation 5 p localized states delocalized states, which efficiently enhances chemical affinity * OOH. Thus, interaction between O atoms greatly facilitates rate‐determining step ( OOH → +O ), realizing high yield rate 10.00 µmol cm −2 h −1 at 1.23 V versus RHE. Furthermore, heterogeneous structure also enhance interfacial electric field (IEF) stability promoting oxygen generation. This work provides an efficient pathway improve photoelectrochemical (PEC) activity manipulating delocalization through defect engineering.

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
