Rational design of porous titanophosphates.

To rationally design new nanoporous materials based on titanophosphates, a small library of titanium phosphate crystalline nanoporous compounds has been build up and its compounds have been investigated by X-ray diffraction and by in- and ex-situ NMR. The main trends of the unusual titanium solution chemistry, of the prenucleation building units and of their assembling have been established. The classical trial and error strategy can therefore be replaced by a better control of the steps leading to the final targeted network.
