POROUS PT/SIO2 CATALYTIC MEMBRANES PREPARED USING MESITYLENE SOLVATED PT ATOMS AS A SOURCE OF PT PARTICLES

The preparation of silica catalytic membrane reactors as well as their characterization are discussed. The deposition of platinum by the Pt mesitylene co-condensate method has proved to provide high Pt loading with good catalyst dispersion, also on SiO2 support. The catalytic activity of the silica membrane has been assessed using the hydrogenation of toluene as model reaction.
