A study on the catalytic activity of a new acidic ordered mesoporous silica (SBA-15)
SBA-15 is an interesting mesoporous silica material having highly ordered nanopores and a large surface area, which is widely employed as a catalyst. This mesoporous silica due to silanol groups is easily functionalized by various organic materials. A new acidic ordered functionalized mesoporous silica (SBA-15-Aminopropyl-Benzyl-SO3H) has been introduced as an efficient catalyst for ...

Lipases find great use in a broad number of biotechnology fields, especially dairy, detergents, drugs (ibuprofen, naproxen), chemicals, agriculture (pesticides, insecticides) and oil chemistry (the hydrolysis of fats and oils).�In order to increase the half-life of the enzyme and repeated use of it, in this study the immobilization of lipase on the mesoporous silica SBA-15 has been investigated...
متن کاملAlkyl surface modification of nanoporous silica SBA-15 by click chemistry to obtain triazole products
In this study, Santa Barbara Amorphous (SBA-15) mesoporous silica has been functionalized with aminopropyl groups that were converted to propargyl-bearing moieties through the reaction with propargyl bromide. The material then underwent an efficient Cu(I)-catalyzed azide alkyne click reaction with sodium azide in order to obtain the corresponding triazole products. The covalent modification of ...
