Two different kinds of titano-silicate zeolite/mesoporous molecular sieves (MMS) materials have been produced following techniques proposed recently in our laboratory. The composite materials designated as UL-TS-1 are obtained by solid phase templated crystallization of a thick walled titanosilicate mesoporous molecular sieves yielding TS-1 nanoparticles in the MMS pore walls. The TS-1 coated mesoporous cellular foams (MCF) are obtained by contacting

TS-1 coated Ti-MCF materials have been prepared by the coating procedure using a diluted clear gel solution containing primary TS-1 nano-crystal units.Various techniques such as BET, TEM, FTIR, 29Si MAS NMR were used to monitor the physico-chemical properties of these samples. The coated samples exhibit higher activity and H2O2 selectivity for 1-naphthol hydroxylation compared to those of the parent Ti-MCF and TS-1 samples. Furthermore, a high hydrothermal
