The use of the template (P123) synthesis method allowed to obtain mesoporous materials of type SBA-15 with thiol and phosphonic groups in the surface layer (SBET = 420-790 m2 / g, Sorb = 0.66-1.01 cm3 / g, dme = 7.7 -8,9 nm). Samples prepared with HCl have a well-developed porous structure characteristic of SBA-15 silica. This synthesis method allows the introduction of a thiol group, while maintaining the structural parameters of SBA-15. Product Description popup.authors Dudarko Oksana A. Melnyk Innа V.
