Monitoring of the Structure of Mesoporous Silica Materials Tailored Using Different Organic Templates and Their Effect on the Adsorption of Heavy Metal Ions

Monolithic supermacroporous hydrogel prepared from high internal phase emulsions (HIPEs) for fast removal of Cu 2+ and Pb 2+

“…Therefore, the porous materials with active functional groups that display high efficiency and affordability are important and necessary to be developed [25,26]. Among the commonly used methods including direct templating, block copolymer selfassembly, and direct synthesis [27,28], freeze-drying is the simplest way to prepare aligned porous inorganic, organic and composite materials [29][30][31]20], but the pore size and pore structure can't be easily tuned via freeze-drying. From an application perspective, the direct templating methodology is a versatile approach to product highly porous polymers with connected pores and tunable pore size [32][33][34], such as high internal phase emulsion (HIPEs) technique.…”

Advanced Nanomaterials for Nuclear Energy and Nanotechnology

“…A mesoporous material is a material containing pores with diameters of 2–50 nm, according to IUPAC nomenclature. Mesoporous materials, such as activated carbon and silica, have received tremendous attention in various scientific areas due to their large surface area, well‐defined pore size, excellent mechanical resistance, nonswelling, and exceptional chemical and radiation stabilities . These extraordinary properties of mesoporous carbon and silica compounds have led the material to be a promising candidate for nuclear waste disposal.…”

Sorption of acid dye by surfactant modificated natural zeolites

“…Total cation exchange capacity (CEC) and the external CEC (ECEC) of zeolites were measured using Haggerty and Bowman [35] method.…”

“…Generally zeolites possess a net negative charge, thus due to isomorphic substitution of the cations in the crystal lattice, they are excellent adsorbents for cationic sorbates [35]. Accordingly, this negative surface charge results in zeolites having little or no affinity for anions.…”
