| Abstract: | In this contribution, hierarchical micro-/meso-porous SiO2 xerogels were successfully prepared through a Stöber methodology coupled with following drying process. The SiO2 xerogels were consisted of nanoparticles of 20–40 nm in size with different contents of water. Fourier transform infrared spectroscopy proved that Si | |
