To achieve hybrid ZrO2 nanocomposites, strong complexing ligands were commonly used as stabilizing agents for non-silicate metal alkoxides precursors [15].
It represents a mixture of silicates, metals, and carbonaceous materials.
Several nanostructural materials (silicate clay, metal nanoparticles, and cellulose nanocrystal) were applied as functional properties for food packaging systems; for example, antimicrobial properties and oxygen scavenging.
In this paper, three-dimensional (3D) hierarchical flower-like metal silicate, including magnesium silicate, zinc silicate, nickel silicate and cobalt silicate, were for the first time prepared by using rice husks as a sustainable silicon source.
In particular, the nutrients (especially phosphate, nitrate, and silicate), heavy metals (e.g., mercury, manganese, copper, lead), and polychlorinated hydrocarbons (DDT, for example) have attracted interest because of their role in ecological problems.
Dihydrogen production may be limited due to decreased Fe(II) oxidation and the fast and favorable incorporation of Fe(II) into carbonates, silicates, and metal hydroxides.
X-ray diffraction showed that the smelter dusts were composed primarily of sulfides, oxides, sulfates, and silicates of metal ores, with galena being the primary dust component.
Air pollution can include residual oil fly ash (ROFA), an inorganic mixture of silicates and metal salts containing vanadium, zinc, iron, and nickel released during the combustion of low-grade oil (Henry and Knapp 1980; Samet et al. 2002).
A series of transition metal silicate hollow spheres, including cobalt silicate (Co2SiO4), manganese silicate (MnSiO3) and copper silicate (CuSiO3.2H2O, CuSiO3 as abbreviation in the text) were prepared via a simple and economic hydrothermal method by using silica spheres as chemical template.
As a typical member of metal silicate hydroxides, nickel silicate hydroxide (Ni3Si2O5(Ohas) has a layered structure formed by outer octahedral Ni II O6 sheets and inner tetrahedral SiO4 sheets [10].
The developed method allowed obtaining the mesoporous oxides and silicates of metals with high crystallinity and given morphological parameters.
