Reinforced Hole Trapping in S‐Scheme Photoharvesters for Markedly Enhanced Photocatalytic Hydrogen Evolution and Nitrogen Fixation

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

Published: March 7, 2025

Abstract The S‐scheme heterojunction exerts a profoundly positive influence on enhancing carrier separation efficiency and redox capability. However, there are few reports accelerating the reaction rate of photogenerated charge carriers, particularly consumption holes in heterojunction. Herein, an situ construction strategy is employed to construct ultra‐small nonprecious metal NiO (≈2 nm) By incorporating into heterojunctions, photocatalytic hydrogen production performance significantly improved by 380 times, nitrogen fixation enhanced 20 times. Density function theoretical (DFT) calculations, X‐ray photoelectron spectroscopy (in XPS), Diffuse Reflectance Infrared Fourier Transform Spectroscopy DRIFTS) characterization results indicate that incorporation heterojunctions can not only enhance photo‐generated carriers ability but also further promote sacrificial agents, thereby achieving secondary enhancement efficiency. Therefore, (H 2 ) (N markedly improved. successful execution this work provides novel approach material structure design, offering valuable insights for development improvement high‐performance materials.
