Abstract

In this study, our research was focused on the synthesis and characterizing of novel mixed metal–metal organic frameworks (MM-MOFs) incorporating porphyrin ligands. Furthermore, we investigated their performance in photodegrading 1,5-dihydroxynaphthalene (1,5-DHN) into 5-hydroxy-1,4-naphthalenedione (Juglone). Integrating metalloporphyrin-based ligands into bimetallic MOFs represents a pioneering advancement in this field. Photocatalytic reactions were conducted using various stoichiometric ratios of Co and Zn as metal nodes, along with meso-tetra(4-carboxyphenyl)porphyrin (TCPP-H₂) and Mn(III) meso-tetra(4-carboxyphenyl)porphyrin chloride (Mn-TCPP) as linkers. Results revealed that Co as a node led to the formation of nanorod metal–organic frameworks (MOF) structures, while Zn enhanced photocatalytic activity. Significantly, a photodegradation yield of 72% was achieved with a 1:3 molar ratio of Co to Zn in Zn_75%/Co₂₅ (TCPP-Mn), demonstrating a synergistic interplay between Co to Zn nodes and Mn-porphyrin linkers. Characterization was performed using structural and microscopic methods. Additionally, various parameters were optimized to elucidate the photocatalytic mechanism, revealing the promising potential of MM-MOFs for efficient photodegradation of 1,5-DHN and beyond. It is noteworthy that the integration of metalloporphyrin-based structures into MM-MOFs for photodegradation processes is relatively uncommon, underscoring the novelty and potential significance of incorporating porphyrin-based ligands in mixed metal MOFs for photodegradation applications.

利用基于金属卟啉的混合金属-金属有机框架，将 1,5-DHN 光降解为生物相容性化合物 juglone：合成、表征和光催化行为

在本研究中，我们的研究重点是合成和表征含有卟啉配体的新型混合金属-金属有机框架（MM-MOFs）。此外，我们还研究了它们在将 1,5-二羟基萘（1,5-DHN）光降解为 5-羟基-1,4-萘醌（Juglone）方面的性能。将金属卟啉配体整合到双金属 MOF 中代表了这一领域的开创性进展。研究人员使用不同化学计量比的 Co 和 Zn 作为金属节点，并使用介-四（4-羧基苯基）卟啉（TCPP-H2）和氯化锰（III）介-四（4-羧基苯基）卟啉（Mn-TCPP）作为连接体，进行了光催化反应。研究结果表明，钴作为节点可形成纳米棒状金属有机框架（MOF）结构，而锌则可增强光催化活性。值得注意的是，Zn75%/Co25（TCPP-Mn）中 Co 与 Zn 的摩尔比为 1:3，光降解率达到 72%，这表明 Co 与 Zn 节点和 Mn-卟啉连接体之间存在协同作用。表征采用了结构和显微方法。此外，还对各种参数进行了优化，以阐明光催化机理，从而揭示了 MM-MOFs 在高效光降解 1,5-DHN 及其他物质方面的巨大潜力。值得注意的是，将金属卟啉基结构整合到 MM-MOFs 中用于光降解过程的情况并不多见，这凸显了将卟啉基配体整合到混合金属 MOFs 中用于光降解应用的新颖性和潜在意义。

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
