Formation of SiO2@NPs (NPs = Ag, Au, CdS) Coatings on Slides from Decane Organogels in the Presence of AOT.

A possibility of isolating gels from organosols of silica by high-speed centrifugation is demonstrated. Organosols of Ag, Au, and CdS nanoparticles (NPs) synthesized in reverse emulsions of AOT are used as the staining additives. Porous rough coatings are molded from the gels by the Doctor Blade method followed by drying and thermolysis at 500°C. The obtained coatings are promising for medical and biological, photovoltaic, and photocatalytic applications. [ABSTRACT FROM AUTHOR]
