Abstract Nanoscale metal-organic frameworks (MOFs) have appeared as potential materials in biomedical and sensing applications. In this work, a nano Zn-BDC-NH2 encoded MOF was effectively synthesized using the co-surfactants strategy and characterized for the curcumin adsorption. The analysis of the synthesized MOF by using characterization techniques, including XRD, SEM, N2 isotherm sorption, TGA, and FT-IR revealed that the nanomaterial exhibited similar structure structural and other physical properties to the original framework, but its particle size was very small of about 50 nm. As a result of the curcumin (CUR) adsorption investigation, the nanomaterial showed a high adsorption capacity on Zn-BDC-NH2 up to 179.36 mg·g−1 and faster adsorption in comparison with reported adsorbents. The results suggest that the nano Zn-BDC-NH2 MOF can be considered as a promising material for bio-applications.

室温合成生物相容性纳米 Zn-MOF 快速选择性吸附姜黄素

摘要 纳米级金属有机框架 (MOF) 已成为生物医学和传感应用中的潜在材料。在这项工作中，使用辅助表面活性剂策略有效合成了纳米 Zn-BDC-NH2 编码的 MOF，并表征了姜黄素的吸附。通过XRD、SEM、N2等温吸附、TGA和FT-IR等表征技术对合成的MOF进行分析表明，该纳米材料表现出与原始骨架相似的结构结构和其他物理性质，但其粒径非常小约 50 nm。姜黄素 (CUR) 吸附研究的结果表明，与报道的吸附剂相比，纳米材料对 Zn-BDC-NH2 的吸附容量高达 179.36 mg·g-1，并且吸附速度更快。
