Recent Advances

Functionalized mesoporous materials are widely used in the environmental field due to their excellent adsorption and catalytic properties. The materials with different functions are obtained by modifying mesoporous materials. In this paper, the preparation methods of functional mesoporous materials with functional groups, metal doping and acid modified were presented. This review focused on the main features and applied prospects of functionalized mesoporous materials under three producing methods. Recent advances of functionalized mesoporous materials in the fields of adsorption and catalysis have been summarized. Adsorption mainly refers to the treatment of heavy metals, organic contaminant, dyestuff and CO2. Finally, the trends and application foreground of functionalized mesoporous materials were elaborated in this paper, which provided reference and guidance for the development of functional mesoporous materials.

The development aims of mesoporous silica formation in pharmaceutical fields were its uses as a drug delivery vehicle and in separation. It is possible because of the large particle surface area, the presence of pores, and the possibility to modify functional groups in the mesoporous materials. In this study, the formation of silica-based mesoporous and boron-silica-based mesoporous materials was carried out by sol-gel techniques and modification of functional groups was carried out by the co-condensation method. Mesoporous material characterization was carried out using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR). Adsorption ability of curcuminoid onto the mesoporous was carried out through isotherm adsorption study approaches using adsorption models including Langmuir, Freundlich, and Temkin model. The results of the isotherm adsorption study showed that the Freundlich model is the best model for isotherm adsorption with an r2 value of 0.997.
