Filter, wash & dry clay samples

  • Clay samples were rinsed with 20 mL DI water + 20 mL ethanol solution 5 times
  • Each time the samples were placed in centrifuge for 20 min
  • Clay was then spread on watch glass in a thin layer and put in oven at 105 C until no moisture was visible
  • Dried clay was ground to a fine powder using a pestle & mortar

Use Au/TiO2 to selectively oxidize an alcohol

  • Glycerol

-Didn't have enough of AuNP that procedures require (0.2 g) so adjusted the amount added of glycerol, methanol, and NaOH

1) Placed 0.15 g AuNP in 100 rbf, added 0.75 g Glycerol, 21.75 mL methanol, and 0.5625 g NaOH

2)Fill a balloon with ~500 mL O2 by reacting 1/2 teaspoon of yeast with 10 mL 3% H2O2 in a flask with holed stopper

3) Placed balloon on 100 mL rbf to introduce O2 into the reaction

4) Reacted for 2 hours and then removed O2 balloon & centrifuge to separate & recover Au/TiO2
