An important aspect that enhances these properties is the proper crosslinking of the materials. Therefore, in this study, we successfully produced films based on a mixture of chitosan and kefiran, crosslinked with kefiran dialdehyde. Our team obtained this crosslinker for the first time, and it is a safe alternative to standard agents such as glutaraldehyde. Moreover, to provide antimicrobial properties of the designed materials, we introduced an extract from the hemp variety “Henola” into the biopolymer matrix. Several analyses were performed to characterize the obtained films (such as FTIR-ATR, AFM, biodegradability, swelling rate, water vapor permeability, and mechanical properties). The biocompatibility of the films was tested using fibroblasts and erythrocytes, and their antimicrobial activity was examined against the bacteria and the fungus. The results showed that crosslinking with dialdehyde kefiran conferred strength and flexibility to the obtained films. Moreover, the film with the ethanol extract showed strong anti-inflammatory properties (86.4 ± 3.67%) and a strong inhibitory effect on the growth of <em>S. aureus</em> (the number of isolated cells was up to 5.7 log lower than that of the control). In addition, the materials do not exhibit hemolysis (≤5%) on contact with blood and are non-toxic to MRC-5 cells (after 24 hours, cell viability above 100%). Therefore, these films have promising potential for practical applications in wound dressing.</p>","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 7","pages":" 2405-2422"},"PeriodicalIF":5.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00029g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740473","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}

A significant advantage is that it exists abundantly in the form of water, natural gas and biomass. However, the drawback is that it exists in the form of compounds and is not available in a free state. Current study was designed to produce hydrogen <em>via</em> catalytic water-splitting reactions. The advantage of the catalytic water-splitting approach is that it is an economical, controllable and more feasible technology. The efficiency of water-splitting reactions can be enhanced by various factors, such as (i) the use of more selective and effective catalysts, (ii) extending the photon absorption capability, (iii) optimizing or predicting the ideal conditions where hydrogen production rates should be maximum, (iv) controlling the charge transfer and (v) increasing the surface active sites by employing metal cocatalysts. For this purpose, stable metal oxides, such as TiO<small>₂</small>, were used as semiconductor supports to promote catalytic hydrogen generation. TiO<small>₂</small> surfaces were tuned with Pd-cocatalysts <em>via</em> controlled hydrothermal reactions, followed by chemical reduction. Catalysts synthesized by this method were found to be more effective in term of water-splitting. The structural and optical properties of the catalysts were assessed <em>via</em> XRD, UV-Vis/DRS, SEM, TEM, AFM, Raman, FTIR, PL, and EIS analytical tools. The phase purity and elemental compositions of the catalysts were confirmed by EDX and XPS techniques. Under similar conditions, photoreactions were performed in a quartz reactor (MICQ/US-150 mL). Hydrogen evolution activities and catalytic performances revealed that the Pd/r-TiO<small>₂</small> catalyst delivers almost ten times higher hydrogen (<em>i.e.</em>, 23.19 mmol g<small>⁻¹</small> h<small>⁻¹</small>) compared to pristine r-TiO<small>₂</small>, which delivers only 2.15 mmol g<small>⁻¹</small> h<small>⁻¹</small> of hydrogen. The higher catalytic performance of Pd/r-TiO<small>₂</small> were attributed to the development of Schottky junctions that escalate and rectify the charge transfer on active sites (<em>i.e.</em>, Pd-cocatalysts).

This study aims to address this gap by synthesizing Cu-doped TiO<small>₂</small> nanoparticles (NPs) and investigating their application as photoanodes in DSSCs to improve energy conversion efficiency. Using a cost-effective and facile co-precipitation method, Cu-doped TiO<small>₂</small> photoanodes were prepared with varying Cu concentrations (0.025 M, 0.05 M, 0.075 M, and 0.1 M) and tested with anthocyanin dye extracted from rose petals. The performance of pure and Cu-doped photoanodes in a DSSC configuration was evaluated using various physical, optical and electrical tools. The photovoltaic and charge transport characteristics were assessed using current density–voltage (<em>J</em>–<em>V</em>) measurements, incident photon-to-electron conversion efficiency (IPCE), and electrochemical impedance spectroscopy (EIS). Among the tested samples, the 0.075 M Cu-doped TiO<small>₂</small> photoanode exhibited superior performance, outperforming both pristine TiO<small>₂</small> and other doping concentrations. When integrated with anthocyanin dye, the DSSC featuring 0.075 M Cu-doped TiO<small>₂</small> demonstrated a notable enhancement in photocurrent density, increasing from 5.8 to 7.6 mA cm<small>⁻²</small>, while the power conversion efficiency (PCE) improved from 1.53% to 2.61%. This enhancement is attributed to the improved light-harvesting capability of Cu-doped TiO<small>₂</small>, along with reduced electron transport resistance and increased recombination resistance, as confirmed by EIS analysis. These findings highlight the potential of Cu-doped TiO<small>₂</small> photoanodes as an effective alternative to pure TiO<small>₂</small> nanostructures for advanced photovoltaic applications.
