Syntheses of ordered mesoporous silica by new hybrid template

Ordered mesoporous silica with macroscopic shape has been prepared with a hybrid template of gel and poly(ethylene oxide) 106–poly(propylene oxide) 70–poly(ethylene oxide) 106 (pluronic F127) surfactant, where both water-soluble agar gel and pluronic F127 significantly affect the mesoporous structur...

Description
Summary:Ordered mesoporous silica with macroscopic shape has been prepared with a hybrid template of gel and poly(ethylene oxide) 106–poly(propylene oxide) 70–poly(ethylene oxide) 106 (pluronic F127) surfactant, where both water-soluble agar gel and pluronic F127 significantly affect the mesoporous structure and morphology of silica. The thermal analysis revealed the noticeable interaction between agar and F127, which contributes to the formation of homogenous hybrid template. In the hybrid template, agar gel contributed to the maintenance of morphology structure, while F127 was responsible for the formation of ordered porous structure in silica solids.
