Rapid and efficient removal of antibiotic pollution in water by photocatalysts is one of the effective means to protect the environment and public health.

Due to their toxicity, efficient removal becomes quite essential. In this report, Ni<img>Al layered double hydroxide (LDH) has been prepared using the coprecipitation methodology for the photocatalytic degradation of reactive dyes. The as-prepared materials were characterized by different techniques, such as DRS, XRD, FESEM, HRTEM, and XPS etc. The XRD pattern of the LDH confirms the formation of the rhombohedral (<em>R</em>3m) phase. The FESEM analysis reveals the irregular hexagon-like shape of the prepared LDH. The Ni<img>Al LDH has 98(1) and 87(1)% photodegradation efficiencies towards the removal of reactive blue 19 and reactive Red 120, respectively. The control experiments in the presence of different scavengers confirm that hydroxyl radicals and superoxide anions participate in photocatalytic degradation. The HRMS studies confirm the formation of different smaller fragments, thereby providing a deeper insight into the photodegradation mechanism. Moreover, the demineralization efficiency (88.9%) is quite close to the degradation efficiency for reactive blue 19, signifying practically complete demineralization of the pollutants. The recyclability studies ascertain the high stability of the photocatalyst. Therefore, the as-prepared Ni<img>Al LDHs can be considered a promising photocatalyst for the removal of reactive dyes from wastewater.</p></div>","PeriodicalId":263,"journal":{"name":"Catalysis Communications","volume":"187 ","pages":"Article 106879"},"PeriodicalIF":3.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1566736724000396/pdfft?md5=506f048d4cd5045085080f8e8670321c&pid=1-s2.0-S1566736724000396-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139924528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, multiple routes have been proposed for obtaining materials with improved catalytic performance versus catalysts with higher molecular transport restrictions. Typically, after the implementation of these treatments, improvement in catalytic activity is correlated either with changes in textural properties (area and porous volume) or the modification of physicochemical properties (Si/Al ratio and acid strength); however, the correlation with diffusional mass transport characteristics is not typical. In this study, alkylaromatic molecules of different kinetic diameters, such as benzene, toluene, p–xylene, and m–xylene, were used as molecule probes to determine the effective diffusion through a pulse experiment under conditions of no adsorption or reaction. The studied solids include five commercial zeolites from the Zeolyst CBV series and four top–down mesostructured Y zeolites. The obtained concentration curves were fitted to an exponential decay model, a solution of the second Fick's law under defined experimental conditions, and correlation values between 0.9996 &gt; R² &gt; 0.9896 were found. Furthermore, the implementation of the descriptors “Transport ratio (TR_MR)” and “Corrected transport ratio (TR_MR^c)” was proposed, which allowed the combined representation of the change in the mass transport of aromatic probes and the changes in the acidity of the zeolite, after the application of top–down treatments. These descriptors proved simple and effective tools to correlate the changes after mesopore insertion with the catalytic performance in the 1,3,5–Triisopropylbenzene (TIPB) cracking reaction. Our approach is an integral method of screening mesostructured zeolites with an adequate balance of acidity and transport properties.</p></div>","PeriodicalId":263,"journal":{"name":"Catalysis Communications","volume":"187 ","pages":"Article 106890"},"PeriodicalIF":3.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1566736724000505/pdfft?md5=b55685ad179631c79999bd79f22c2c3c&pid=1-s2.0-S1566736724000505-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
