Silicate mesoporous materials have received widespread interest because of their potential applications as supports for catalysis, separation, selective adsorption, novel functional materials, and use as hosts to confine guest molecules, due to their extremely high surface areas combined with large and uniform pore sizes. Over time a constant demand has developed for larger pores with well-defined pore structures. Silicate materials, with well-defined pore sizes of about 2.0–10.0 nm, surpass the pore-size constraint (<2.0 nm) of microporous zeolites. They also possess extremely high surface areas (>700 m2 g−1) and narrow pore size distributions. Instead of using small organic molecules as templating compounds, as in the case of zeolites, long chain surfactant molecules were employed as the structure-directing agent during the synthesis of these highly ordered materials. The structure, composition, and pore size of these materials can be tailored during synthesis by variation of the reactant stoichiometry, the nature of the surfactant molecule, the auxiliary chemicals, the reaction conditions, or by post-synthesis functionalization techniques. This review focuses mainly on a concise overview of silicate mesoporous materials together with their applications. Perusal of the review will enable researchers to obtain succinct information about microporous and mesoporous materials.

The β‐cyclodextrin (β‐CD) was successfully applied to synthesize Cu‐SiO2 catalysts by the sol‐gel method. The first and most important question addressed was increasing the copper loading with higher dispersion in the silica support. Another task was to elucidate the structure–performance relationship. Furthermore, catalysts with various β‐CD doping levels were systematically characterized and employed in the hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The 0.1CD‐Cu‐SiO2 catalyst with 17.39 wt % copper showed 99.9 % DMO conversion and the highest EG selectivity of 95.0 % at 210 °C, as well a lifetime of over 240 h. The reaction results disclosed that the catalytic performance could be tuned facilely by changing the amount of β‐CD doping, which effectively influenced the Cu metallic surface area and dispersion.

“…These defects and the slight deviation from linearity are expected if the cobalt is a cast of the lyotropic crystalline phase when it is a soft solid. 25,26 The films are estimated to have a pore center -to center distance of about 9.12 nm, with a uniform pore diameter of about 7.65 nm and cobalt wall thickness of about 4.5 nm. According to the TEM results, it is noted that the mesostructures of the H1-eCo almost remain unchanged under different deposition potentials, which is consistent with the results reported in literature.…”

A simple, inexpensive and less time consuming electrochemical methods were carried out to prepare ordered mesoporous cobalt films. Ordered mesoporous cobalt films were successfully synthesized by templated electrodepostion of hexagonal H1-e Co ion. The electrodeposited mesopores films were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), low angle X-ray diffraction (XRD) and voltammetric methods. The applicability of thin films as high -performance super capacitors electrode materials is demonstrated electrochemically using cyclic voltammetry (CV) technique.
