چکیده:

Sulfuric acid functionalized particles of Silica were synthesized with different sizes and shapes of silica powder. Silica nano-spheres have an average size of 225 nm and silica micro-tube were synthesized and they were functionalized with sulfonic acid. Their acidic properties were investigated with used them in the biginelli reaction as a catalyst.
