A METHOD FOR OBTAINING OF A POROUS SIO2-XEROGEL WITH CHARACTERISTIC SIZE OF THE PORES BY MEANS OF BOTTOM-UP APPROACH USING PRECURSOR WITH ORGANIC SOLID SKELETAL SUPPORTS

摘要

The invention relates to the production of a porous SiO2-xerogel using temporary organic solid skeletal supports that are formed in situ and that are removed by thermal oxidation at the end of the production process, by means of a sol-gel process by subcritical drying of the gel.
