Mesoporous silica coated silica-titania spherical particles: from impregnation to core-shell formation.
The coating of solid surfaces with inorganic materials is a promising approach not only to impart various functionalities but also to modify physicochemical properties that are affected by the geometry/structure of the coating. In this study, a silica-hexadecyltrimethylammonium (silica-CTA) hybrid layer was deposited on monodispersed spherical particles composed of titania and octadecylamine (t...
متن کاملPhotocatalytic Coating Using Titania-Silica Core/Shell Nanoparticles
The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...

متن کاملTitania-Silica Composites: A Review on the Photocatalytic Activity and Synthesis Methods
The photocatalyic activity of titania is a very promising mechanism that has many possible applications like purification of air and water [1]-[4]. To make it even more attractive, titania can be combined with silica to increase the photocatalytic efficiency and durability of the photocatalytic material, while lowering the production costs [1]. In this article, relevant literature is reviewed t...
