One of the most sought-after applications is the photocatalytic oxidation of alcohols to their corresponding aldehydes. There is significant interest in the selective production of compounds such as benzaldehyde, cinnamaldehyde, and vanillin using this technology, among various other valuable components. This work examines common production methods and alternative synthesis routes for aldehydes from their alcohols, focusing on g-C3N4-based photocatalytic schemes. The discussion includes an analysis of g-C3N4 structures that have shown significant results in the selective oxidation of alcohols and provides a critical review of the mechanism, highlighting the importance of reporting quantum yields of the reaction. Literature data suggest that photocatalysis is a viable alternative to traditional aldehyde production methods, with maximum selectivity values towards the product of interest (>99%), but catalytic activity remains limited, with relatively low quantum yields, restricting the transition beyond the laboratory scale. However, the charge handling in g-C3N4-based advanced materials is adequate for this application, and their implementation under solar illumination conditions is promising.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 12","pages":" 3760-3784"},"PeriodicalIF":5.2,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00229j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In light-assisted water treatment, they have so far only been exploited via the hydroxyl radical route, through Fenton-like processes. A new avenue is introduced here by the biomimetic conceptual design of MOF bearing hypervalent metal atoms for photocatalytic water treatment. We report a zeolitic imidazole framework (ZIF) material doped with iron (Fe-ZIF-7-III; UPO-4) synthesized via a novel mild treatment to stabilize photoactive hypervalent ferryl ions for the first time in a MOF for water treatment. The successful synthesis of the 2D material and the adequate incorporation of iron into the structure were demonstrated using X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). A simulation study analyzed the structure and stability of the Fe-ZIF-7-III material as well as the involvement of ferryl ions in the photo-Fenton-type process. Furthermore, the calculated band gap of this material shows its viability for use in photocatalysis using sunlight. This was confirmed by evaluating the photodegradation of caffeine, a model pollutant in water, without the assistance of hydroxyl radicals as indicated by a scavenger test. The recyclability test revealed that Fe-ZIF-7-III could be used continuously with effective catalytic activity, thus opening the door to the field of studying hypervalent metal MOFs not yet explored in water treatment.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 11","pages":" 3612-3621"},"PeriodicalIF":5.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d4ma01217h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesis process involved varying the concentrations of Sm3+ dopants to investigate their impact on the phosphors' structural and luminescent properties. The phase purity of the synthesized material was evaluated using X-ray diffraction (XRD) analysis, which confirmed a hexagonal crystal structure. Additionally, the XRD results validated the high phase purity of the prepared oxyapatite phosphors and demonstrated the successful incorporation of Sm3+ ions into two separate crystallographic sites within the lattice. Raman scattering spectra revealed distinct vibrational modes corresponding to the stretching and bending vibrations of the PO4 and SiO4 groups in the structure of the synthesized material. In addition, scanning electron microscopy (SEM) illustrated the morphology of the sample. The photoluminescence excitation and emission spectra of Ca3La7(SiO4)5(PO4)O2:Sm3+ phosphors were investigated. Upon excitation with near-ultraviolet (near-UV) light, the phosphors exhibited four distinct emission peaks at wavelengths of 565 nm, 598 nm, 648 nm, and 708 nm. Ca3La7(SiO4)5(PO4)O2:Sm3+ phosphors exhibit strong orange-red emission centered at 598 nm, attributed to multipole–multipole interactions, and demonstrate rapid decay rates, making them promising candidates for temperature sensing and supplementary solid-state lighting applications. The CIE chromaticity coordinates of phosphors with varying Sm3+ concentrations consistently fall within the orange-red region, confirming their characteristic light emission.

However, the traditional synthesis routes used to prepare these Y2Ru2−xYxO7 electrocatalysts require calcination at temperatures higher than 1000 °C for extended periods of time, resulting in highly sintered particles. We propose an alternative synthesis route, a glycine combustion method, that reduces the calcination time to only two hours to obtain porous pyrochlores. These pyrochlores contain a small RuO2 impurity phase that is eliminated when the combusted product is calcined for nine hours instead of two. When the combustion synthesis is combined with a molten salt synthesis (MSS), there is no impurity phase, but large pyrochlore crystallites in a porous matrix are produced. The electrochemically active surface area (ECSA) is an order of magnitude lower than the other pyrochlores prepared, negatively affecting the electrocatalytic activity. In addition to altering the fuel and calcination conditions used in the synthesis, the oxidiser : fuel ratio (ϕ) has also been altered to manipulate the intensity of the combustion reaction. A ϕ = 1, an explosive reaction takes place. The intensity is reduced to a slow burn when adjusting ϕ to 0.3. The synthesised pyrochlores have been analysed with X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS) and Raman spectroscopy. They have also been tested as OER electrocatalysts in 0.5 M H2SO4.

Ethylenediamine and Procion red are introduced onto PGMA microspheres with high concentrations of 10.2 N wt% and 39.1 wt%, respectively. Due to such heavy introduction of chemically bonded dyes, the molar extinction coefficient reached up to 3.28 × 1011 L mol−1 cm−1, which significantly exceeds that of commercially used colloidal gold nanoparticles (9.44 × 109 L mol−1 cm−1). Based on the colored PGMA microspheres, we propose a drop casting and photo scanning protocol to find the minimum detectable particle density of the microspheres. As a result, the Procion red bonded PGMA microspheres could be easily identified with a density as low as 4.43 × 104 particles per mm2. Finally, when applied to COVID-19 antigen detection, the microspheres achieved a sensitivity of 0.025 ng mL−1 and exhibited broad pH (3–11) and long-term (7 months) stability and high specificity.

We propose the use of hyaluronic acid-conjugated pH-sensitive liposomes to deliver prednisolone (LipoHA:PDP) to activated macrophages. Materials & methods: we evaluated the cytotoxicity and targeting potential of LipoHA:PDP using the THP-1 cell line. Results: LipoHA:PDP significantly inhibited the release of inflammatory mediators and reduced NF-κB translocation to the nucleus. The liposomes also decreased reactive oxygen species (ROS) production. Moreover, LipoHA:PDP prevented albumin denaturation, which impacts immune recognition, inflammation, and tissue damage.
