Abstract

The solution thermal decomposition-precipitation (ThDP) of oxide precursor inside the nanotubes (nanoreactors) of mesoporous silica support under atmosphere saturated with solvent at the oxide precursor decomposition temperature was explored for loading the W-oxide nanoparticles into SBA-15. ThDP of W-Ethoxide solution in decalin yielded WO3/SBA-15 composites with W-phase located exclusively inside the pores in form of nanocrystals strongly blocking the pores. ThDP of W(CO)6 yielded W-phase up to 32 wt% spread as an amorphous monolayer on the pore walls with minimal pore blocking.
