Lastly, the synthesis of Fe-MOFs by doping with other metals or adding several agents provides an effective way to accelerate the redox cycle of Fe\({}^{3+}\)/Fe\({}^{2+}\) and promote the radical generation and/or increase the selectivity of the catalysts by the removals of the pollutants present in the wastewater. However, although more than one thousand studies have been published in the last five years about this topic, there is still a long way to go for Fe-MOFs to be consolidated as catalysts and to be viable for large-scale use. Compiling this collection of studies, it is possible to say that this future is not very far away. The prospect of their usage for Fe-MOF based AOPs presents several aspects and future opportunities related to the removal of emerging pollutants:  
* Eco-friendly preparation of MOFs: search for alternative methods for MOF synthesis with high yield and using environmentally friendly and harmless solvents. * Bimetallic MOFs: application of various transition metals in the synthesis of the MOF enhancing their properties for the AOPs;
* New composite materials hybridized with MOFs: exploration of new materials to be introduced on MOFs adding new functions and achieving high-performance of the catalyst. * Shelf life and reusability: these are prerequisites for long-term industrial use. The improvement of the stability of MOFs for their use in aqueous environments is required because most of them are unstable in water and decompose.
