SiO2 PARTICLE EMBEDDED SILICA AEROGELS: ENVIRONMENTAL AND ENERGY APPLICATIONS
Abstract
The purpose of the study is the preparation of silica aerogels by using the hydro(solvo)thermal synthesis assisted sol-gel method, the preparation of SiO2 particle-added silica aerogels, and the investigation of their potential use in the environment and energy fields. It has been observed that the prepared silica aerogels can be used as an adsorbent for organic contaminant removal applications. It has been observed that silica aerogels progressed rapidly in the reaction of NaBH4 with methanol as SiO2 particle embedded silica aerogel.
