Optimization of mesoporous titanosilicate catalysts for cyclohexene epoxidation via statistically guided synthesis

An efficient approach to improve the catalytic activity of titanosilicates is introduced. The Doehlert matrix (DM) statistical model was utilized to probe the synthetic parameters of mesoporous titanosilicate microspheres (MTSM), in order to increase their catalytic activity with a minimal number of experiments. Synthesis optimization was carried out by varying two parameters simultaneously: homogenizing temperature and surfactant weight. Thirteen different MTSM samples were synthesized in two sequential 'matrices' according to Doehlert conditions and were used to catalyse the epoxidation of cyclohexene with tert-butyl hydroperoxide. The samples (and the corresponding synthesis conditions) with superior catalytic activity in terms of product yield and selectivity were identified. In addition, this approach revealed the limiting values of each synthesis parameter, beyond which the material becomes catalytically ineffective. This study demonstrates that the DM approach can be broadly used as a powerful and time-efficient tool for investigating the optimal synthesis conditions of heterogeneous catalysts. Abbreviation

“…Inorganic materials with rigid pore structure are able to overcome the polymer upper bound. Zeolite, Metal Organic Framework (MOF), ceramic and silicate membranes have the potential to deliver high selectivity or good stability; however, the large-scale application is inhibited by the expensive fabrication cost and their brittle natures [23][24][25][26][27][28][29][30].…”

“…At 473 K, the CO 2 /N 2 and CO 2 /CH 4 selectivities dropped to 20 and 52, respectively [132] . Titanosilicate ETS-10 is characterized with three-dimensional 12-ring pore system (0.76 × 0.49 nm) [133,134] . ETS-10 membranes could separate CO 2 from binary mixtures of CO 2 and N 2 or H 2 , due to the CO 2 preferential adsorption and diffusion.…”

Over the past two decades, membrane technology has attracted tremendous attention at CO 2 separation from other gases, which has shown great potential to significantly improve energy efficiency and reduce cost associated with processes. The membrane structures and chemistry properties greatly affect their CO 2 separation performances, including selectivity and permeability. In recent years, there has been significant progress in the development of CO 2 -selective membranes. This chapter reviewed the recent activities relating to the fabrication and separation performances of polymeric, inorganic and mixed-matrix membranes for CO 2 separation purposes.
