Versuchsvorschrift

Hesperidin/silver colloidal nanoparticle catalyst is prepared by dissolving 1.65 g hesperidin in a beaker containing 800 ml DI water at room temperature. 1 N NaOH solution with stirring is added to adjust the solution pH to 11. In a separate beaker, 2.2 g silver p-toluenesulfonate is dissolved in 60 ml DI water. The silver ion solution is added to the hesperidin solution with strong stirring. The molar ratio of silver to hesperidin is 1:0.34. 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.
