Herein, ultra-fine Al₂O₃ nanofibers which are further self-assembled to form uniform rod-like morphology (R–Al₂O₃) were fabricated via a facile sol-gel strategy and further utilized as support to dispersing vanadium species (V/R–Al₂O₃). The physicochemical properties of the samples were systematically characterized by XRD, Raman, SEM, TEM, H₂-TPR, CO₂-TPD, XPS, and ²⁷Al MAS NMR techniques. It is found that except that R–Al₂O₃ support has the merits of a high specific surface area, lager pore volume, and uniform mesopore structure, the presence of the unsaturated pentacoordinate Al³⁺ ions plays a pivotal role in better dispersing V active species, with the existence of the isolate and/or polymeric forms. As compared to V/C–Al₂O₃ (commercial Al₂O₃ as support), the V/R–Al₂O₃ catalyst endows outperformed catalytic performances for oxidative dehydrogenation of ethylbenzene in the presence of CO₂ (OEBDH-CO₂). In which, the V/R–Al₂O₃ catalyst gives a high EB catalytic activity and good stability without significant deactivation phenomenon being detected even after the third regeneration test. Such a result can be principally ascribed to that R–Al₂O₃ support with excellent textural properties can better disperse V species so as to expose more active sites, which is beneficial for improving the conversion efficiency of EB. More importantly, keeping/regaining high valence state of V species in the V/R–Al₂O₃ catalyst under CO₂ as a soft oxidant effectively promotes Mars-Van Krevelen redox cycle, further suppressing the catalyst deactivation. This work provides a rational design strategy for a high efficiency and stable dehydrogenation catalyst by optimizing the textural properties of Al₂O₃ support and introducing the unsaturated pentacoordinate Al³⁺ ions.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"340 ","pages":"Article 130818"},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760272","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}

Selective laser melting (SLM) of porous biomaterials shows potential, but challenges such as unmelted powder on the surface affect material quality and dimensional accuracy. Considering the complex solution environment in the human body, corrosion resistance is crucial for implanted materials. In this study, a radial gradient porous scaffold is designed using a Gyroid unit cell structure and fabricated by SLM, followed by sandblasting. The forming accuracy, microstructure, mechanical properties, and electrochemical corrosion behavior in simulated body fluid (SBF) are investigated before and after sandblasting. Sandblasting effectively removes adhering powder, improving pore size accuracy and reducing porosity error from 1.41 %-1.69 % to 0.15 %–0.38 %. Grain size decreases, grain density increases, and unmelted voids are eliminated. However, the passivation film is damaged, reducing corrosion resistance, with a tenfold increase in corrosion current density compared to the original samples. After sandblasting, the elastic modulus increases from 7.84–8.83 GPa to 8.08–9.02 GPa, and the yield strength improves from 292.02–328.31 MPa to 300.17–336.73 MPa, enhancing the scaffold's load-bearing capacity.

Intriguingly, the presence of a very low level of H₂S gas (∼0.5 ppm) in the air can be detected by humans due to its characteristic pungent smell. However, upon constant exposure to H₂S, the sense of smell gets dissipated due to olfactory paralysis, resulting in a false sense of safety and consequently leading to fatal conditions. Recently, luminescent metal organic frameworks (LMOFs) have emerged as novel platforms for gas sensing applications due to their superior optical properties and high porosity. In the current work, we report the fabrication and sensing behaviour of a LMOF coated fibre-optic sensor probe for highly sensitive and real-time detection of hydrogen sulphide gas under ambient conditions. The sensor probe was fabricated by functionalising the end tip of a silica-based optical fibre with silver-based LMOF. The constituent silver ions of LMOF not only provided reactive sites for H₂S gas, but the resulting interaction also offers a highly sensitive photoluminescence quenching-based sensing mechanism for sustained detection of H₂S. Additionally, we also deduced that the integration method of LMOF has a marked effect on the overall sensing performance. The sensor probe can detect H₂S in real time with a lower limit of detection at 0.085 ppm.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"340 ","pages":"Article 130815"},"PeriodicalIF":4.3,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759752","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}
