Not all that glitters… The activity of supported gold nanoparticles depends on the method used for their preparation. Gold clusters of about 2 nm in diameter were deposited on nonreducible metal oxides and carbon materials by solid grinding of a volatile organogold complex in a ball mill and subsequent calcination (see scheme). Au/ZrO 2 and Au/Al 2 O 3 prepared in this way were extremely efficient catalysts for the aerobic oxidation of glucose.
