In this presentation, UiO-66-NH2 MOFs were in-situ grown accompanied by alginate (Alg) hydrogelation under aqueous conditions, achieving UiO-66-NH2/Alg composite hydrogels. Relevant characterizations demonstrate the in-situ generated UiO-66-NH2 MOFs were evenly distributed in hydrogel networks by attaching on Alg fiber surfaces. The network structure became denser, but both specific surface area and pore volume were augmented due to the presence of MOFs, which in turn increased active sites to interact with adsorbates. Thus, the adsorption capacity to methylene blue (MB) of composite hydrogels became higher with more dosage of MOF ligand, and the pH sensitivity of Alg adsorption to MB in the pH range of 4 to 10 was eliminated. Furthermore, the study of adsorption kinetics and isotherm reveals MB adsorption on the obtained hydrogels belong to rate controlling chemisorption mechanism. In summary, this manuscript presents a facile approach to realizing the green synthesis and shaping of Zr-MOFs by one-step compositing of UiO-66-NH2 with Alg-based hydrogels in aqueous system, achieving MOFs-based composite hydrogels with enhanced MB adsorption.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"10 12","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861589","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}

However, the high supersaturation of the precursor solution leads to the rapid formation of a significant number of nuclei and a diminished concentration of perovskite solute. Consequently, the inadequate availability of precursors poses challenges in sustaining the subsequent crystal growth phase, culminating in the development of small-sized single crystals. In this work, we report a controlled nucleation process to foster the growth of large-size single crystals. This method through the coordination interaction between polyacrylic acid and Pb2+ ions, and substitution of the coordination with I− ions. This reduces the formation of the Pb-I6 complex, which promptly emerges in a state of supersaturation and acts as a nucleus, thereby effectively reducing the number of nuclei formed. The single crystals produced using this method exhibit a lateral size exceeding 5 mm, an extended absorption range, a longer carrier lifetime of 10.93 ns, and enhanced stability. These crystals demonstrate the ability to remain stable even after storage in an ambient environment (T=20±5 °C, RH=60±5 %) for a period of 20 days.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404642","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}

Here, chemically bonded BA−Co-Melamine precursors are initially constructed using different BA fractions as substrate, Co2+ as bridge bond and melamine as ligand. A series of Graphene/N-CNTs hybrids (GNCs) is eventually synthesized after the precursor pyrolysis. Resultantly, Fraction I, separated at a pH value of 4.16, plays a significant role on constructing the BA−Co-Melamine precursor and further producing multiholed GNCs. Due to abundant CNTs, rich mesopores, moderate nitrogen incorporation and a certain graphitized assembly structure, the prepared GNC-I-b has high capacitance performances. The assembled AC//GNC-I-b supercapacitor has high specific capacitance (147 F g−1 at 1 A g−1), rate capability, cycling stability and energy density (16.8 Wh kg−1 at 14.4 kW kg−1). The 2032 coin-type Li//GNC-I-b half-cell has high initial discharge capacity (759 mAh g−1 at 0.03 A g−1), initial Coulombic efficiency (81.8 %), rate performance and cycling stability.

To improve their practical application and recyclability, we propose a hybrid composite of biocompatible MOFs decorated on self-supported three-dimensional (3D) printed polyurethane acrylate (PUA) for wastewater treatment. In this study, we select Bi-based MOFs with good visible-light response and chemical stability as photocatalysts, two MOFs, bismuth gallate (Bi-GA) and bismuth ellagic acid (Bi-EA), are loaded into the mesh-like PUA template by in-situ growth method. And then, these two composites, PUA/Bi-GA and PUA/Bi-EA are used for the photocatalytic treatment of Rhodamine-B (RhB) dye. The results demonstrate that PUA/Bi-EA could reach the highest removal rate of 98.08 % under acidic conditions in 4 hours. The excellent performance should be attributed to unique structure that endow their high adsorption capacity for dyes, further, the adsorbed dye as a sensitizer enhances the utilization of sun-light.
