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 stability of the mesopore structure and the absence of any Ti
leaching during reaction were observed for the coated samples. This could be due to the zeolitic nature and
hydrophobicity of the coated samples mesopore surface.
