The functionalized silica for the synthesis of metal nanoparticles includes a silica surface functionalized by a hydrazino-triazine derivative. A method of preparing the functionalized silica includes the steps of combining silica gel and a triazine derivative in a first organic solvent to form a mixture; heating the mixture for about two hours; isolating a white solid by filtration; washing the solid with the first organic solvent; suspending the white solid in a second organic solvent to form a suspension; adding hydrazine hydrate to the suspension while stirring; heating the suspension for about 3 hours to form the silica surface functionalized by a hydrazino-triazine derivative; and isolating the silica surface functionalized by a hydrazino-triazine derivative by filtration.
