Synthesis and characterization of sulfur-containing hybrid materials based on sodium silicate
Autor: O. A. Dudarko, Sandor Barany
Publikováno v: RSC Advances. 8:37441-37450
An original method for the one-stage synthesis of sulfur-containing silica of SBA-15 type is developed and described. Instead of tetraethylorthosilicate (TEOS) typically used as a source of silica, the inexpensive sodium metasilicate has been applied
