MOFs Hosting Sol-Gel-Based Structures

Different strategies can be utilized to grow sol-gel materials on MOF supports and the classification can be made according to the fabrication protocol involved. 

Although the integrity of the MOF is required and moisture-sensitive MOFs are involved, the classical sol-gel strategy that requires wet conditions (presence of H2O) might cause incompatibility. Fischer and coworkers developed an alternative strategy to form metal oxides inside MOFs overcoming the potential 

In summary, the above-mentioned papers used an initial infiltration procedure to develop sol-gel-based materials into MOFs. 

The third method is the one-step formation of MOF-sol-gel composite materials. This requires carefid selection of the synthetic conditions that should enable the simultaneous formation of the sol-gel network and MOF crystaL For
