Fluorinated metal-organic frameworks such as KAUST-7, KAUST-8 are stable in acidic environment.

Hi Alireza,

Some MOFs are designed to be stable in acidic environments, but most tend to degrade due to their sensitivity to moisture and low pH. However, a few MOFs have shown good stability in acidic conditions, such as:

1. Zirconium-based MOFs (e.g., UiO-66 and UiO-67): Zirconium (Zr) MOFs are highly stable in both acidic and aqueous environments due to the strong Zr-O bonds. UiO-66, in particular, can withstand acidic conditions with a pH as low as 1-2.

2. Aluminum-based MOFs (e.g., MIL-53, MIL-101): Aluminum (Al) MOFs like MIL-53 and MIL-101 also demonstrate good stability in acidic environments due to the strong metal-ligand bonding.

3. Chromium-based MOFs (e.g., MIL-101(Cr)): Chromium (Cr) MOFs, especially MIL-101(Cr), show stability in acidic media, making them suitable for certain applications under low pH.

The choice of metal and linker in MOF design plays a key role in determining their acid resistance. I hope this will help you.

Thank you for your good answer.

Can MOFs be made with pyrite nanoparticles?

Hi Alireza,

Greetings for the day!!

I am very sorry for not responding sooner.

Now, coming to the answer, if you want to use pyrite nanoparticles as a linker for MOF synthesis, the answer would be no since linkers in MOFs are typically organic molecules that form coordination bonds with metal ions, not inorganic nanoparticles. However, pyrite nanoparticles can still be integrated into MOFs through other strategies: 1) Embedding Pyrite Nanoparticles within MOFs, 2) Pyrite as the Metal Source for MOF Synthesis, and 3) Surface Modification.

I hope this will help you.

Hello, thank you
