The direct mixing method is a simple, fast, and cheap alternative that allows for MOF production at room temperature in times as short as 15 min. The room-temperature synthesis via a direct mixing method of Ni and Mg MOFs based on trimesic acid (BTC) and terephthalic acid (BDC) was studied by evaluating the effect on the product of the synthesis parameters: pH, base, stirring time, and metal–ligand molar ratio. It was found that the base used to adjust the pH was a critical factor to ensure the formation and purity of each MOF, where Na⁺ from NaOH could alter the crystal structure of Mg MOFs by incorporating into it due to its size similarity with Mg²⁺, while the ability of K⁺ from KOH to enter the crystal structure was much lesser due to its larger size and allowed for the proper development of the Mg MOFs crystal structure Similarly, a higher molar ratio of the ligand to the metal resulted in the incorporation of the base’s metal into the MOF as an impurity due to an excess of ligand without enough metal to coordinate with. Pure Ni-BTC and Ni-BDC MOFs could be obtained in ~ 15 min, while the Mg-BTC MOF always contained the base-forming metal as an impurity. All the products had irregular morphologies which resulted in lower surface areas and pore volumes when compared to MOFs obtained by other methods. The improvement of these properties is crucial to make the direct mixing method a viable alternative as higher surface areas and pore volumes are beneficial for many of the applications of MOFs, and it was identified that the choice of metal salt precursor plays an important role over these properties. As such, experimentation with different precursors is an important avenue of future research for the improvement of this method.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 4","pages":"2065 - 2077"},"PeriodicalIF":2.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tailorable structure, pore size, surface area, and fluorescence of MOFs have led to their applications in diverse fields such as catalysis, sensing, gas storage, and photovoltaic. In the present study, a water-stable and dispersible iron-based MOF, i.e., NH₂-MIL-53(Fe), was hydrothermally synthesized, and demonstrated for the fluorescent detection of tetracycline (TC) antibiotic. The fluorescence of as-prepared NH₂-MIL-53(Fe) was quenched in the presence of TC due to the bonding between OH (of TC) and –NH₂ (of NH₂-MIL-53(Fe). This effective fluorescence quenching of NH₂-MIL-53(Fe) in the presence of TC can be attributed to a combination of the inner filter effect (IFE) and photo-induced electron transfer (PET) process from the ligand of NH₂-MIL-53(Fe) to TC, as described by theoretical and experimental studies. Under the optimum conditions, the ratio of fluorescence intensity and TC concentration showed a good linear range (0.05–1 µM) with a detection limit of 53 nM. Furthermore, the sensing probe was also used to detect TC in the spiked milk and juice samples with good recoveries, i.e., 91.3–98.5% and 95.7–104%, respectively. These results demonstrated the potential of NH₂-MIL-53(Fe) nanosensor to detect TC in real food samples.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 3","pages":"1891 - 1902"},"PeriodicalIF":2.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11696-025-03896-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CO₂ temperature-programmed desorption (CO₂-TPD) confirmed the CO₂ uptake capacity of CaO/USY at medium temperatures (300 °C). Among the CaO/zeolite adsorbents synthesized, the 10% CaO/USY exhibited the highest adsorption capacity at 300 °C, with a CO₂ uptake of 34.94 mmol·kg⁻¹ during the first cycle. The adsorbent also maintained its CO₂ capacity at 21 mmol·kg⁻¹ over the next nine cycles. Physicochemical analysis revealed that the porous volume of the 10% CaO/USY adsorbent was 0.28 cm³·g⁻¹, and its substantial surface area was 506.20 m²·g⁻¹, as determined through N₂ adsorption measurements. Characterization using FTIR and FESEM confirmed the successful loading and uniform dispersion of CaO on USY, respectively. X-ray diffraction (XRD) analysis revealed that 10% CaO/USY exhibited a smaller CaO crystallite size (29 nm) compared to bulk CaO (65 nm) and 15% CaO/USY (32 nm). Additionally, XRD identified the presence of calcium silicate salts (CaSiO₃ and Ca₂SiO₄) and calcium aluminate salts (Ca₁₂Al₁₄O₃₃), which reduce the CO₂ capture capacity but enhance cyclic stability. This finding suggests a potential approach to enhancing the effectiveness of adsorbents by optimizing the conversion of CaO into these salts. The results provide valuable insights for advancing and scaling up CaO/zeolite adsorbents for CO₂ capture.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 3","pages":"1927 - 1943"},"PeriodicalIF":2.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal conditions were found to be 466 W of power, 39 min of irradiation, and 33% NaOH concentration, which resulted in extraction yields of 88% for cellulose.

Investigations were conducted on the use of natural sawdust (NSD) and activated sawdust (ASD) to remove BR2 dye from an aqueous medium. To chemically modify the ASD, 1 M caustic soda solution (NaOH) was used. By adding novel functional groups (–ONa) to the ASD surface, the sorption efficiency of the BR2 dye was improved. This resulted in a considerable increase in surface polarity and sorption site power. Using FTIR, EDX, and (SEM) analysis, the structure and morphology of adsorbent sawdust were examined. The batch technique generated quantitative adsorption under a range of circumstances, including initial concentration, pH, temperature, and contact time. The adsorption kinetics were investigated using two kinetic models, including pseudo first order and pseudo second order, and a pseudo second-order kinetic is the best model. Two common isotherm equations (Langmuir and Freundlich) are that were used to determine the BR2 dye adsorption isotherms on adsorbents and showed a good fit with the Langmuir model more than Freundlich’s isotherm model (<i>R</i>² = 0.995). The thermodynamic assessment demonstrated the exothermic, spontaneous, and feasible nature of the BR2 adsorption onto NSD and ASD. The results clarified that a large percentage removal and the optimized conditions were (8 ± 0.01) solution pH, 19.28 mg/L initial dye concentration, adsorbent dose 0.1 g/40 ml of dye solution for NSD and ASD respectively, and 60 min adsorption time. 68.72% and 93.77% of dye were removed by NSD and ASD respectively at experimental optimum conditions. The removal price per gram of BR2 dye in 1000 m³ of wastewater using ASD adsorbent was found to be 0.017$ which is very low compared to another adsorbent. The BR2 removal efficiency is still above 85% and 60% after four cycles concerning ASD and NSD respectively. Additionally, NSD and ASD are easily regenerative and reusable, suggesting that this adsorbent may have significant promise for wastewater dye adsorption.
