HKUST-1 (or HKUST MOF) is a popular metal-organic framework (MOF) material consisting of copper ions coordinated to 1,3,5-benzenetricarboxylic acid (BTC) linkers. It is commonly used in various applications, including catalysis, gas storage, and sensing.

To disperse HKUST-1 for UV-Visible spectroscopy and particle size analysis, a common solvent used is N,N-dimethylformamide (DMF). DMF is a polar aprotic solvent that is able to dissolve HKUST-1 without significantly affecting its structure or properties. Other solvents such as ethanol and methanol may also be used, but they may not be as effective as DMF.

It is important to note that the choice of solvent can affect the dispersion and stability of HKUST-1, as well as the properties of the resulting dispersion. The solvent should be carefully selected based on the specific requirements of the experiment or application. Additionally, the concentration of HKUST-1 in the solvent should be optimized to ensure accurate and reliable measurements.

Febin Cherian John Thanks for your answer. However I tried to disperse the MOF (

If you have already tried various solvents and solvent combinations and the MOF particles are still settling down quickly, it could be an indication that the particles are not well-dispersed, and there may be some agglomeration or aggregation of the particles.

In this case, you may want to consider using a surfactant to stabilize the dispersion. A commonly used surfactant for MOFs is Pluronic F127, which is a non-ionic triblock copolymer that can help prevent particle agglomeration.

To use Pluronic F127, you can dissolve it in water or a suitable solvent, and then add the MOF particles to the solution while stirring or sonication. The Pluronic F127 will adsorb onto the surface of the MOF particles and help to stabilize the dispersion.

Another option is to modify the surface of the MOF particles with a functional group that can improve their dispersibility. For example, you can use a silane coupling agent such as 3-aminopropyltriethoxysilane (APTES) to modify the surface of the MOF particles and make them more hydrophilic.

Additionally, you may want to try increasing the concentration of the MOF particles in the solvent to improve their dispersibility. However, it is important to note that higher concentrations may also increase the likelihood of particle agglomeration or aggregation, so you will need to find the optimal concentration for your specific experiment.

Overall, optimizing the dispersibility of MOF particles can be a complex and challenging process, and it may require some trial and error to find the best approach for your specific application.

I hope this helps Sir

Febin Cherian John Thank you very much for your answer, i will check on this
