Robust and Sustainable Synthesis of Al-Based MOFs form Waste Aluminium

Current synthetic methods, however, rely on a variety of aluminium salts for synthesis of MOFs within the same family and are not the most efficient sources of aluminium. Herein, we demonstrate a robust synthetic pathway to MOFs CAU-9, CAU-10 (-NO2,-NH2,-N3), CAU-10-py, CAU-15, CAU-21, MIL-53(Al)-TCD, MOF-303 and Al-Fum from aluminium formate, a compound that we have previously synthesized from industrial aluminium waste.

We replace commercial aluminium salts with sustainably sourced aluminium, reducing the amount of waste and harmful byproducts, all by using a common aluminium precursor.
