Structural insights of mechanochemically amorphised MIL-125-NH$_2$

In this work, we investigated the response of the metal–organic framework MIL-125-NH$_2$ to ball-milling. Both localised and bulk analyses revealed prolongued ball-milling results in a complete loss of long-range structural order. Investigation of this disorder revealed partial retention of the local bonding of the secondary building unit, suggesting structure collapse progressed primarily through metal–linker bond breakage. We explored the photocatalytic performance of the materials, and examined the materials’ band gap using UV-Vis reflectance spectroscopy.
