“…A large decrease in specific surface area in the case of ceria modification of MCM-41 is probably caused by high loading of ceria (32 wt. %) and probably by partial distortion of the mesoporous hexagonal phase [20].…”

“…Especially low initial rates were found for Fe-Beta-150. The first order rate constant determined by XPS and basic sites measured by CO 2 TPD can be found in [20]. It was recently reported in the literature [29], that neither only weak Lewis nor weak Brønsted acidic homogeneous catalysts were able to catalyze Prins cyclization of homoallylic alcohol with 2-methoxybenzaldehyde.…”

Mesoporous solid bases are extremely desirable in green catalytic processes, due to their advantages of accelerated mass transport, negligible corrosion, and easy separation. Great progress has been made in mesoporous solid bases in the last decade. In addition to their wide applications in the catalytic synthesis of organics and fine chemicals, mesoporous solid bases have also been used in the field of energy and environmental catalysis. Development of mesoporous solid bases is therefore of significant importance from both academic and practical points of view. In this review, we provide an overview of the recent advances in mesoporous solid bases, which is basically grouped by the support type and each category is illustrated with typical examples. Cooperative catalysts derived from the incorporation of additional functionalities (i.e. acid and metal) into mesoporous solid bases are also included. The fundamental principles of how to design and fabricate basic materials with mesostructure are highlighted. The mechanism of the formation of basic sites in different mesoporous systems is discussed as well.

“…The removal of water produced during reaction in time was the research topics in recent years. The alternative route of one-pot reaction from CO 2 and ethanol in the presence of epoxide as a dehydration agent was reported to enhance the DEC yield [16,17]. Nevertheless, the raw materials of epoxides were relatively expensive.…”
