Best KAUST-7 Powder Metal Organic Frameworks (MOFs) Service, Exporter

KAUST-7 is also known as NbOFFIVE-1-Ni. KAUST-7 has longer Nb–O and Nb–F distances compared to Si–F (1.899 Å for Nb–F vs. 1.681 Å for Si–F). This resulted in larger anionic octahedra pillaring the square grid thus reducing the pore size. KAUST-7 have attracted widespread attention because of their high chemical stability and thermal stability, outstanding tolerance with water and H2S, and high CO2 adsorption selectivity over H2 and CH4.
