Effect of ammonia concentration on the properties of silica nanoparticles / Siti Nurul Nadia Rosdiansah

Silica nanoparticles were prepared by Stober method using tetraethoxysilane as precursor, and ammonia as catalyst- The silica nanoparticles then were functionalized with silane coupling agent, 3-aminotriethoxysilane (APTES) to show the feasibility of anchoring functional group NH2 on silica nanop...
