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.

Regulation of the Built‐In Electric Fields of MIL‐125(Ti)@Ti‐Ce‐MOF Yolk‐Shell Z‐Scheme Heterojunctions via Ligand Defects Toward Optimized Photocatalytic Performances

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Окт. 23, 2024

Abstract The controllable formation of a built‐in electric field (IEF) can effectively separate photogenerated electrons and holes optimize the band structure material, thus improving its photocatalytic performance. Here, novel type defective metal‐organic framework (MOF), i.e., an MIL‐125(Ti)@Ti‐Ce‐MOF yolk‐shell Z‐scheme heterojunction, is synthesized using simple ion‐etching‐coupled reconstruction method. By controlling concentration ligand defects within MOF strength IEF heterojunction be regulated. Moreover, experimental theoretical results demonstrated that enhance efficiency carrier separation improve transport capacity by regulating IEF. tetracycline (TC) degradation performance resultant ≈52.5‐ 5.5‐fold higher than those Ti‐Ce‐MOF MIL‐125(Ti), respectively, indicating efficient spatial charge due to enhanced This study reveals precise control over elucidating relationship between defect promoting performances MOF@MOF‐based catalysts via density functional theory related experiments.
