Mechanochemical activation of solids can lead to a strong increase in their activity as catalysts in heterogeneously catalyzed reactions. In the following, we report on the effects of solid catalyst activation during ball milling that lead to oscillatory behavior in CO and CO2 formation during propene oxidation. The oscillations arise under in situ ball milling conditions over …...The mechanical milling was performed in a horizontal oscillatory mill (Retsch, PM 400) operating at 25 Hz. The mixture ratio of steel balls and ZnO powders was around 15:1 by weight percent. The milled materials were used directly with no added milling media. Five balls were kept in each cell along with 10 g of the sample powder.
