In-situ mesoporous silica pillared clay synthesis and

Oct 01, 2020 Fe-SPC structures were in the form of a mesoporous clay gallery in which the iron species (presumably oxide) were homogeneously distributed on the surface of clay leaves and small numbers of larger particles were collected together (Picture 2, Picture 3c) [41,42]. In contrast to titanium metal, it was found that iron metal had better interaction with silica.

Ilmenite Wikipedia

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Occurrence, properties, and uses. Titanium is widely distributed and constitutes 0.44 percent of Earth ’s crust. The metal is found combined in practically all rocks, sand, clay, and other soils. It is also present in plants and animals, natural waters and deep-sea dredgings, and meteorites and stars.
