The sulfides were produced through simple precipitation methods, without the necessity of complex methodologies or equipment. Additionally, the effect of thermal treatment on the properties of the Bi₂S₃ samples was also evaluated. The choice of the sulfide precursor imparted distinct characteristics onto the synthesized Bi₂S₃, such as distinct morphologies, specific surface areas (SSA), and crystalline structures. Notably, the efficiency of Cr(VI) photoreduction was found to be intricately linked to the adsorption capacity of Bi₂S₃. In this context, the calcination process emerged as a significant impediment, as it substantially diminished both the SSA and adsorption capacity of the materials. Among the sulfide sources investigated, Bi₂S₃ synthesized using K₂S exhibited superior photoreduction efficiency, attributed primarily to its remarkable adsorption capacity and rod-like morphology. The photoreduction mechanism was determined to be carried out by the direct reaction between Cr(VI) and photogenerated electrons. Regarding operational parameters, initial concentration, pH and temperature had major effects on the photoreduction efficiency; high initial concentrations led to the saturation of the active sites and lower reaction rate constants, whereas lower pHs and higher temperatures favored the photoreduction process. As for the recycle tests of the best photocatalyst, it was discovered a significant efficiency loss between cycles, which was linked to the occlusion of active sites through the formation of chrome-based species on the surface of the photocatalyst.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"112 2","pages":"568 - 581"},"PeriodicalIF":2.3,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced characterization techniques such as XRD, SEM, TEM, FT-IR, Raman spectroscopy, and XPS, alongside UV-vis spectroscopy and VSM measurements, highlighted the profound impact of Gd³⁺ doping. Notably, the incorporation of Gd³⁺ led to nano-sized cubic structures with an optimized crystallite size of 19.82 nm in the ZMF4 sample, and a notable reduction in the band gap from 3.21 eV to 2.99 eV was observed, indicative of enhanced electronic properties. Magnetic analysis revealed a transition towards superparamagnetic behavior, with a decrease in coercivity and squareness ratios, suggesting applications in areas such as data storage and optical waveguides. Furthermore, the study leveraged FLUKA Monte Carlo simulations to assess the gamma-ray shielding efficiency of these materials. It was found that increasing Gd³⁺ concentration or sample thickness markedly improved radiation attenuation, highlighting the material’s enhanced shielding capabilities against a range of photon energies. The most significant findings included the optimized sample (ZMF4) displaying superior magneto-optical characteristics and outstanding gamma-ray shielding performance, especially at higher Gd³⁺ levels.

For this purpose, perovskite oxides have attracted significant interest as effective electrocatalysts for oxygen evolution reactions (OER) in response to their highly adjustable catalytic and electrical properties associated with their compositions. This study presents a novel hydrothermal approach to fabricate SrSnO₃/rGO composite in order to accelerate the four electron transfer mechanisms. Moreover, the physical analyses show that cubic-shaped SrSnO₃ are irregularly dispersed in the form of spherical on the nanosheets of rGO. Compared with pristine, the BET study shows that composite exhibits a greater surface area (59 m² g⁻¹). To evaluate the catalytic kinetics, conductivity and stability, the electrochemical evaluation of the electrode material (SrSnO₃/rGO) was performed in alkaline media with Ni foam (NF) as substrate. The exceptional electrocatalytic performance of the material in the OER could be associated with its unique structure, many active sites, and favorable conductivity. This performance is characterized by fast reaction rates, as indicated by a minimal Tafel constant (33 mV dec⁻¹) along with reduced overpotential (199 mV) at 10 mA cm⁻². Moreover, the chronoamperometry (CA) investigation of the SrSnO₃/rGO composite indicates 35 h of long-term stability.

Paperbag is a recently proposed term to denote oligonuclear complexes not featuring intrinsic metal-metal bonding and thus not qualified to be called “clusters”. Another important insight, provided recently by the studies of heterometallic species, is dealing with visualization of bonding modes of single atom catalysts on metal oxide substrates and reveals possible coordination environments of heteroatoms on doping. The studies of large paperbag aggregates can contribute to understanding of factors influencing the bandgap and photocatalytic activity of related oxides.

We developed a novel sol-gel fabrication method of Er³⁺/Yb³⁺doped silica microspheres with a homogeneous doping concentration over the entire microsphere volume. The sol-gel precursors were doped with 1–2 mol% Er³⁺ and/or Yb³⁺. The viscosity of the precursor was controlled at around 4000 cP, and gel fibers can be conveniently drawn from the precursor.

The diameters of microspheres were determined by the fiber diameter and laser parameters, such as laser power and irradiation time duration.

A new bacterial culture medium was prepared using a cost-effective and available type of fungus, <i>Terfezia spp</i>. At the same time and using the green method, titanium oxide nanoparticles (TiO₂ NPs) were mycosynthesized using the same fungus. In a novel manner, the TiO₂ NPs were loaded into polyvinyl alcohol/sodium alginate (PVA/SA/TiO₂ NPs) aerogel beads, which were prepared using the sol-gel method and freeze-drying cycle. These nanocomposite aerogel beads were characterized using several techniques such as UV-vis, FTIR, SEM, and XRD. Bacterial growth analysis showed successful growth of all pathogenic bacterial samples on the <i>Terfezia spp</i>. culture medium. The UV-vis analysis for PVA/SA/TiO₂ NPs exhibiting a characteristic peak within 260–290 nm. FTIR characterization demonstrated the successful mycosynthesis of TiO₂ NPs using <i>Terfezia spp</i>. and interaction between the TiO₂ NPs and polymer. SEM revealed the TiO₂ NPs had spherical morphology with an average size around 38 nm while the aerogel bead surface showed a uniform nanoporous structure. XRD analysis indicated the TiO₂ NPs was incorporated into the PVA/SA matrix. The mycosynthesized TiO₂ NPs exhibited broad-spectrum antibacterial activity against pathogenic bacterial strains, with zones of inhibition ranging between 24–34 mm, while the antimicrobial activity of the PVA/SA/TiO₂ NPs aerogel beads ranged between 12–20 mm, as indicated by the well diffusion assay. The minimum inhibitory concentration (MIC) of the TiO₂ NPs was found to range between 16–64 μg/mL, while the minimum bactericidal concentration (MBC) values were determined to be between 8–32 μg/mL for the tested pathogenic bacterial strains. Growth kinetics testing showed that the PVA/SA/TiO₂ NPs aerogel beads exhibited complete inhibition against all pathogenic bacterial strains, in contrast to the pure PVA/SA aerogel beads. The antibacterial performance was directly related to the loading of the TiO₂ NPs in the polymer matrix.
