反応手順
Myricetin 3-rhamnoside/silver colloidal nanoparticle catalyst is prepared by dissolving 1.04 g myricetin 3-rhamnoside in a beaker containing 750 ml DI water at room temperature. With stirring, 1 N NaOH solution is added to adjust the solution pH to 11. In a separate beaker, 1.4 g silver p-toluenesulfonate is dissolved in 40 mL DI water. The silver ion solution is added to the myricetin 3-rhamnoside solution with vigorous stirring. The molar ratio of silver to myricetin 3-rhamnoside is 1:0.4. The beaker containing the aqueous catalyst solution is placed in a 50° C. water bath for 12 hours to test its stability. After 12 hours the solution is observed and no precipitate is expected indicating that the catalyst is still stable.
