Popis: Oxide films of nominal composition of 80SiO2⋅20TiO2 were coated using partially hydrolyzed complex alkoxide solutions on the porous silica which had mesopores of about 3 nm width and narrow pore diameter distribution (PDD). After coating, the larger pores present in the porous silica decreased and the PDD became narrower. No micropores were observed even after coating. No apparent effect on PDD was observed by the repetition of the coating procedure.
