As found, introducing nickel acetate into the resorcinol-formaldehyde gels does not lead to the reduction of Ni or the formation of large Ni particles. Due to the even distribution of acetate ions in the organic xerogel matrix, their decomposition occurs at a temperature of ~520 °C, when the matrix is almost disintegrated. This gives additional amounts of carbon oxides, which are released at this temperature and affect the porous structure. Carbon xerogel containing 2.5 wt% Ni possesses the lowest density (0.54 g/cm³) and the largest pore volume (1.62 cm³/g). Compared with pure carbon xerogel, this sample retains high values of the external (278 m²/g) and total (783 m²/g) specific surface areas and does not undergo graphitization. It is worth noting that pH has little effect on the porous structure of carbon xerogel doped with a low amount of nickel. Contrarily, varying the concentration of resorcinol and formaldehyde in the solution allows obtaining Ni-doped carbon xerogels with tunable pore radius ranging from 16 to 200 nm and density in the range of 0.27–0.80 g/cm³. On the other hand, the textural properties of the xerogel matrix were found to influence the agglomeration process of nickel particles during the pyrolysis stage. In the case of mesoporous and macroporous xerogels, the agglomeration of Ni particles is hindered due to the texture limitations or the blockage of small nickel particles inside the matrix.</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":"114 2","pages":"625 - 640"},"PeriodicalIF":2.3,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830777","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}

This study investigates the synthesis and application of films of vertically and intricately aligned titanium dioxide (TiO₂) rods, fabricated by etching to enhance surface properties, and subsequently decorated with molybdenum disulfide (MoS₂) for the degradation of Methylene Blue (MB). The etching process is crucial in creating more active sites on the TiO₂ rods, improving their ability to interact with light and reactants. The MoS₂ decoration was implemented with different reaction durations. The photocatalytic performance of each sample was evaluated over 10 h with MB concentration of 5 ppm at pH 12. Comprehensive characterizations of the MoS₂-decorated etched-TiO₂ rods films were conducted using X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM), and ultraviolet–visible spectrophotometry (UV-Vis) to elucidate their structural, morphological, topological and dye degradation properties, respectively. Photocatalytic performance was assessed under visible radiation. The results demonstrated that the etched-TiO₂ rods, decorated with MoS₂ for 7 h, exhibited the greatest MB degradation efficiency, with a 47% improvement over the as-deposited TiO₂ and a 31.13% increase compared to the etched-TiO₂ rods film. This significant enhancement with etching treatment is attributed to improved crystallinity, surface morphology, and surface roughness facilitated by the optimal MoS₂ decoration.

In the present work, <i>Azadirachta indica</i> leaf extract (AILE) was applied in a green synthesis approach to create cobalt chromite nanoparticles (CoCr₂O₄ NPs). This approach makes the process straightforward, simpler, benign, and cheaper, which requires less effort to produce CoCr₂O₄ NPs. The characterization of CoCr₂O₄ NPs was explored using diverse analytical techniques. According to the XRD diffractograms, CoCr₂O₄ NPs were obtained in the cubic phase. TEM disclosed their pseudo-spherical morphology with a mean diameter of 54.89 nm. The bandgap of CoCr₂O₄ NPs was found to be 2.39 eV, which allows for UV absorption and makes them ideal for effective photocatalysts under sunlight. Conversely, under direct sunlight, the photocatalytic potential of CoCr₂O₄ NPs was examined employing malachite green (MG) dye as a pollutant model. After 90 min, a decomposition of 91.33% was accomplished, revealing pseudo-first-order reaction kinetics. In addition, the influence of H₂O₂, CoCr₂O₄ loading, MG dye concentration, and scavengers on the MG photodegradation was also verified.
