“…unstable structure and poor adsorption capacity; in order to improve the physical and chemical properties of the material, the structure and surface of MCM-41 are modified to meet specific practical requirements [35]. In this aspect, constructing organic-inorganic hybrid frameworks to enhance the properties of MCM-41 has attracted more and more interest [36,37]. For instance, Mohammadnezhad et al [38] fabricated MCM-41/PS for adsorption of Cd(II).…”

A novel functional hybrid mesoporous composite material (CMP) based on chitosan and MCM-41-PAA was reported and its application as an excellent adsorbent for Hg(II) ions was also investigated. Innovatively, MCM-41-PAA was prepared by using diatomite and polyacrylic acid (PAA) with integrated polymer–silica hybrid frameworks, and then CMP was fabricated by introducing MCM-41-PAA to chitosan using glutaraldehyde as a cross-linking agent. The structure and morphology of CMP were characterized by X-ray diffraction, Fourier transform infrared spectra, thermogravimetric analysis, scanning electron microscopy and Brunauer–Emmett–Teller measurements. The results showed that the CMP possessed multifunctional groups such as –OH, –COOH and –NH2 with large specific surface area. Adsorption behaviour of Hg(II) ions onto CMP was fitted better by the pseudo-second-order kinetic model and the Langmuir model when the initial Hg(II) concentration, pH, adsorption temperature and time were 200 mg l−1, 4, 298 K and 120 min, respectively, as the optimum conditions. The corresponding maximum adsorption capacity could reach 164 mg g−1. According to the thermodynamic parameters determined such as free energy, enthalpy and entropy, the adsorption process of Hg(II) ions was spontaneous endothermic adsorption.

“…In another study, Wei et al 26 , stated that a rise in the amount of SBA‐15 increased the molecular weight, the T g value, and storage modulus but decreased the monomer conversion in the PMMA/SBA‐15 composite prepared via free radical polymerization (FRP) of methyl methacrylate (MMA). Researchers have also used the mesoporous silicates as a nanoreactor for absorbing the monomers due to their high ordered porous structure.…”

In the present work, boron‐acrylate/Santa Barbara Amorphous (SBA)‐15 polymer composite was synthesized using free radical polymerization method. Firstly, SBA‐15 was functionalized with 3‐(trimethoxysilyl)propyl methacrylate to obtain chemically bonded boron acrylate (BAc) polymer on the SBA‐15 surface. The structural analysis was evaluated via Fourier‐transform infrared spectroscopy and solid‐state nuclear magnetic resonance 13C. Samples were also characterized by using scanning electron microscopy, X‐ray powder diffraction, N2 adsorption/desorption and thermogravimetric analysis. In order to examine the BAc polymers in the mesopores, the silica framework was removed via hydrofluoric acid etching process. The results indicated that the synthesis of boron‐acrylate/SBA‐15 polymer composite was performed successfully. Thermal stabilities of the composites were higher with greater amounts of BAc polymer in mesopores under oxidative conditions.
