Construction of two isomorphic multifunctional MOFs via a dual-ligand strategy for aromatic compounds detection and photocatalytic degradation performance
The development of multifunctional and structurally unique metal−organic frameworks (MOFs) presents a highly attractive yet challenging endeavor for chemists. In this study, we employ a dual-ligand strategy to synthesize two isomorphic Co/Zn MOFs, {[Co4(BMIP)3(MIP)4]·3DMF·H2O}n (SNUT-35-Co) and {[Zn4(BMIP)3(MIP)4]·2DMF·2H2O}n (SNUT-35-Zn). The photocatalytic performance of SNUT-35-Co and SNUT-35-Zn was evaluated using methylene blue (MB). Under UV/visible-light irradiation, the photocatalytic decolorization rates of MB for SNUT-35-Co and SNUT-35-Zn reached 95 % within 140 min and 120 min, respectively, indicating their superior degradation. Notably, SNUT-35-Zn demonstrated exceptional detection capabilities for aromatic compounds, such as aniline and nitrobenzene, at lower concentration range without interference from other components. The detection limits for these two small molecules were found to be 0.430 and 0.431 μM, respectively. Additionally, both MOFs exhibited large transient photocurrent and low impedance in electrochemical measurement. The results suggested that the photocatalytic activities of MOFs are influenced by their three-dimensional structures, which facilitate electrons passing due to the inherent semiconductor properties.
期刊介绍：
The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including:
• Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.)
• Chemical intermediates
• Molecules in excited states
• Biological molecules
• Polymers.
The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example:
• Infrared spectroscopy (mid, far, near)
• Raman spectroscopy and non-linear Raman methods (CARS, etc.)
• Electronic absorption spectroscopy
• Optical rotatory dispersion and circular dichroism
• Fluorescence and phosphorescence techniques
• Electron spectroscopies (PES, XPS), EXAFS, etc.
• Microwave spectroscopy
• Electron diffraction
• NMR and ESR spectroscopies
• Mössbauer spectroscopy
• X-ray crystallography
• Charge Density Analyses
• Computational Studies (supplementing experimental methods)
We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
