Abstract:

Mesoporous silica nanoparticles have received much more attention in recent years due to their unique structures with organized porosity, high surface area, and specific pore volume, which have several potential applications in the field of adsorption, separation, sensors, and fuel cells. Moreover, substitutions of metals in the silica framework have yielded fruitful results in the field of catalysis. Over the different kind of mesoporous materials, we had investigated several organic reactions such as aza-Michael, Pechmann reaction for synthesis of coumarin, β-hydroxy esters/α, β-carbonyl compounds and 1, 5-dicarbonyl compounds via Mukaiyama-aldol and Michael reactions, Friedel-Craft alkylation, β-amino alcohol via ring opening of epoxides with indole/pyrole/aromatic amines, etc. The products are mainly used as starting/intermediate compounds for preparation of an insecticide such as hymecromone, anticoagulants, as additives in food and cosmetics, etc. The detail synthesis and thorough characterization of the mesoporous materials shall be focused in the presentation. The synthesized catalysts have the potential activities as mentioned above reactions. The all catalysts could be reused for several recycles. The catalytic activities were found to be decreased gradually as increasing the recycles. This is mainly because of the leashing of the metal or active compound from the materials. The detailed results on the effect of the different weight percentage, reaction temperature, active sites and textural parameters will be discussed during the presentation.
