Structural and optical characterization of hemimorphite with flower-like morphology synthesized by a novel low-temperature method

Basic Characteristics of Hemimorphite and Its Transformation Mechanism with Na2CO3

“…This software package is the first-principle method based on density functional theory (DFT). Hemimorphite is a nesosilicate mineral and an orthorhombic system [13,14]. It contains a 3D spatial skeleton formed by a connected vertex between Si-O double tetrahedra and Zn-O tetrahedra in its crystal structure.…”

Three-Dimensional Assemblages of Metal Silicate for Catalytic CO2 Conversion to Methanol and Adsorptive Pollutant Removal

“…16,29,30 Inorganic layered materials, for example, which possess solid frameworks with high aspect ratios and two-dimensionally confined nanospaces in their interlayers, have also been utilized for various applications, such as adsorbents, catalysts and/or catalyst supports, ion exchangers, and fillers for resins. 31,32 Many inorganic layered materials (host materials) can accommodate various guest species in the interlayer. As silica is an important catalyst carrier in a catalyst, in this work, we developed a synthetic strategy to make layered silicate-based supported nanocatalysts as well as an adsorbent for organic pollutants.…”

“…Due to their high surface areas, low material and processing costs, abundant supply, and chemical inertness, silica and silicate-based materials have attracted great attention in recent years. − Within these silica and silicate materials, silicon-oxygen tetrahedrons with four negative charges (SiO 4 4– ) are the basic building units, which can be linked to each other in different modes, leading to various anionic structures or oligomers such as single units, double units, chains, rings, and so on. Therefore, silica/silicate materials have been widely used in a wide range of applications, such as drug delivery carriers, adsorbents of heavy metal ions, catalyst supports, etc. , In recent years, various integrated nanostructured transition-metal silicates and phyllosilicate with different morphologies and higher surface areas than their silica precursor have been fabricated. ,, Inorganic layered materials, for example, which possess solid frameworks with high aspect ratios and two-dimensionally confined nanospaces in their interlayers, have also been utilized for various applications, such as adsorbents, catalysts and/or catalyst supports, ion exchangers, and fillers for resins. , Many inorganic layered materials (host materials) can accommodate various guest species in the interlayer.
