Microwave synthesis of Zr incorporated SBA-16 mesoporous silica as a catalyst for Meerwein-Ponndorf-Verley (MPV) reduction

Zr incorporated and pure SBA-16 were prepared by microwave synthesis method. These microwave synthesized Zr-SBA-16 played a role as Lewis acid sites for the Meerwein-Ponndorf-Verly reduction of ketones giving almost 100 % selectivities with high activities.

Microwave synthesis of SBA-15 mesoporous silica material for beneficial effect on the hydrothermal stability

Hydrothermally robust mesoporous SBA-15 silica material was synthesized for the first time using microwave with out adding any other chemical ingredients. For the sake of stability comparison, mesoporous SBA-15 material was also prepared by conventional hydrothermal technique. The stability of the material was tested by boiling water method and 29 Si-NMR Q 4 /Q 3 ratios. It was observed that SBA-15 synthesized under microwave conditions exhibited higher stability than that of hydrothermally synthesized SBA-15.

Facile Synthesis of Mesoporous Silica Nanotubes With Amide Type Surfactant

Novel synthetic method for the formation of mesoporous silica nanotubes was proposed using glycyldodecylamide (GDA) as an amino acid surfactant, which enabled to control the tube diameter, wall structure and morphology with the diverse structures of amphiphile due to the capability of H-bonds by forming amide bond. Moreover, this sol-gel transcription process could be elucidated at neutral condition that enabled the recyclable use of surfactant and resulted in unique structures depending on the temperatures of self-assembly.Copyright
