Synthesis of Cu nanoparticles in mesoporous silica SBA-15 functionalized with carboxylic acid groups.
In this study, the mesoporous silica SBA-15 materials containing carboxylic acid groups were used as an effective support to synthesize Cu nanoparticles. Various Cu loading levels from 4% to 13% on SBA-15 catalysts produced an average particle size of 2.8 to 3.1 nm, regardless of the Cu content.

متن کاملA 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 ...

متن کاملApplication of Sulfonic Acid Functionalized Nanoporous Silica (SBA-Pr-SO3H) in the Green One-pot Synthesis of Polyhydroacridine Libraries
1,8-Dioxo-decahydroacridines have been synthesized by the three-component reaction of aromatic aldehydes, aromatic amines (or ammonium acetate), and dimedone in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) under solvent-free conditions. Excellent yields, short reaction times, mild reaction conditions, an...
