Here, we report the synthesis of a novel heterostructure nanocomposite made of Nb₂O₅/ITIC-4F/CuO to be employed as an efficient solar-driven photocatalyst for enhancing hydrogen generation capacity. The in-situ monoethanolamine-assisted colloidal synthesis leads to the modulation of the morphology and structure of the Nb₂O₅/ITIC-4F/CuO nanocomposite. This synthetic recipe leads to the creation of chemical bonds between the ITIC-4F and the surfaces of the Nb₂O₅ and the CuO nanostructures, thereby reducing the interfacial resistance between the grain boundaries of the formed heterojunction, and the light absorption of the entire system has shifted toward the visible spectrum region. The XPS measurements showed that the LUMO level of the ITIC-4F falls below the LUMO level of CuO and above the LUMO level of Nb₂O₅. These unique features facilitate the charge transfer from CuO to Nb₂O₅ and hinder the electrostatic repulsion between the n-type and p-type electrons. The photoelectrochemical, electrochemical impedance spectroscopy, and optoelectronic measurements revealed that the ITIC-4F provides active sites for effectively gathering photoinduced electrons and reduces the charge-transfer resistance at the electrode/ electrolyte interface. The optimal hydrogen production rate of the Nb₂O₅/ITIC-4F/CuO heterostructure is 187 mmol.h⁻¹.g⁻¹. Interestingly, this hydrogen rate is larger than the CuO/Nb₂O₅ nanocomposite (14 mmol.h⁻¹.g⁻¹) by <strong>10 times</strong> under visible-light illumination. Therefore, this study provides a novel heterojunction architecture with precise structural engineering to convert solar energy to chemical energy efficiently.</div></div>","PeriodicalId":18265,"journal":{"name":"Materials Research Bulletin","volume":"190 ","pages":"Article 113532"},"PeriodicalIF":5.3,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to investigate the effects of unit cell design on the uniaxial compressive properties and fracture mechanism of SLM Al-8.3Fe-1.3V-1.8Si lattice. The results show that the compressive strengths of the body-centered cubic (BCC) and face-centered cubic with Z-axis strut (FCCZ) samples were 109 MPa and 298 MPa, respectively. In the FCCZ sample, the strain first concentrated at the interconnections between the Z-axis and diagonal struts and gradually extended into the Z-axis strut. The Z-axis struts could effectively endure the compressive stress and then buckle without cracking, resulting in the high and wide first maximum compressive peak up to 25 % strain. Due to the large first maximum compressive peak and the stable stress in the plateau and densification areas, the energy absorption at 50 % strain of the FCCZ sample was as high as 86 ± 3 MJ/m³. Furthermore, the SLM Al-8.3Fe-1.3V-1.8Si lattice with the FCCZ unit cell exhibited better compressive strength and energy absorption than those of SLM Ti-based metallic lattices in the literature with comparable relative densities. Thus, SLM Al-8.3Fe-1.3V-1.8Si lattice is a promising candidate for high-strength and lightweight applications.
