Catalyst synthesis

There are several options to obtain an active catalyst, but whichever you choose you should be aware that all the preparation steps have a great influence on the final result. It is thus important to design accurately the synthesis procedure, taking care of both the catalyst desired properties and the scalability and sustainability of the whole preparation process. Beside the conventional synthesis routes (e.g. impregnation, precipitation etc), in our group we are now involved in the study of the mechanochemical synthesis for the deposition of metals onto the surface and subsurface of oxide carriers, and in the preparation of thermally stable high surface area supports. Both topics are of great interest in light of an increased interaction between the active phase and the support and of an enhanced catalytic activity. The fine tuning of all the synthesis steps is achieved by the continuous feedback coming from the catalyst characterization and from selected catalytic tests.
