Bridged Mesoporous Oxo Phosphonates for Separation and Catalytic Applications – BMOP4App

We have recently developed a low-cost synthetic methodology leading to mesoporous nonsiliceous hybrid materials with controlled texture and functionality. These nanomaterial are easily obtained by reaction of metal oxide precursors (e.g. Ti(OiPr)4) and many rigid bisphosphonate esters. These materials are stables in aqueous media between pH 1 and pH 12, and it was also shown that functional organic groups can be easily incorporated and remain accessible. The unique combination of texture, functionality, and stability makes these promising materials complementary of other hybrid materials such as periodic mesoporous organosilicas or MOFs. By combining expertise of all partners, our aim is to design new hybrid materials for raw sewage treatments and to capture specifically some elements for recycling. A particular interest will be focus on the use of these materials for the recovery of strategic metals such as platinoids or molybdenum and try to use them directly for specific catalytic experiments.
