Metal-Organic Frameworks (MOFs) have a wide range of applications in fields such as adsorption and separation, gas storage, catalysis, biomedicine, and sensing. However, the majority of MOF synthesis still requires energy-intensive methods such as hydrothermal and solvent-thermal methods, and as solid powders, MOFs are difficult to recover after adsorption and have poor reusability. Therefore, optimizing synthesis and preparing recyclable devices are necessary for the commercialization of MOFs. Traditional forming processes such as granulation and compression reduce the functionality of MOF materials, so preparing MOF composite materials is a necessary step to improve economic efficiency. This paper explores two methods for preparing MOF mixed matrix membranes and 3D printed MOF devices to improve the recyclability and economic efficiency of MOFs. Specifically, we first synthesized a pair of supramolecular isomers [CdL(H2O)]·Phenol·2H2O (1) and [CdL(H2O)]·3H2O (2) of H2L=H2(Me-4py-trz-ia)=5-(3-methyl-5-pyridyl-1,2,4-triazole) isophthalic acid through solvent regulation and studied their adsorption behavior of phenol in phenolic wastewater and simulated fuel. The experimental results showed that the maximum adsorption amount of compound 1 in phenolic wastewater was 126 mg/g, while compound 2 had no adsorption effect; in simulated fuel, the maximum adsorption amount of compound 1 for phenol was 215 mg/g, while the maximum adsorption amount of compound 2 was 193 mg/g. By comparing the adsorption behavior of these two compounds, we confirmed the difference in adsorption performance between the two supramolecular isomers, with compound 1 being superior to compound 2. Therefore, we used compound 1 as an inorganic filler to prepare adsorption mixed matrix membranes and investigated the effect of different filler contents on membrane performance. The results showed that the membrane had a retention rate of 83% for phenol in phenolic wastewater and 99% in phenol-simulated fuel. Secondly, MAF-4 (ZIF-8) has become a classic representative of MOF research due to its high crystallinity, high chemical stability, simple synthesis, uniform pore size distribution, and excellent adsorption properties, widely used in separation, catalysis, sensing, and other fields. To further explore the application of MAF-4, we mixed it with sodium alginate and gelatin to prepare a gel with good rheological properties and successfully prepared a 3D printed MAF-4 single piece using direct ink writing by adjusting 3D printing parameters. After characterizing the obtained 3D printed MAF-4 by SEM, XRD, 77 K nitrogen adsorption-desorption tests, TGA, and other methods, we confirmed the successful loading of MAF-4. This adsorbent can not only be used for dye adsorption but also be stably regenerated and reused at least 5 times. The experimental results showed that the removal rate of Congo red dye by MAF-4 with a 33.3 wt% loading amount was above 90%. This indicates that 3D printed MAF-4 has good application prospects and can achieve efficient adsorption of pollutants by adjusting its loading amount.
