His team investigated whether a catalytic reaction in such a mill works better because the catalyst is always given a fresh surface where the reactants can meet. They used a soft alumina (gamma-alumina) mixed with gold particles as a catalyst and followed the process in the ball mill with various analytical methods.
When using non-piezoelectric ceramic materials, such as TiO 2, BaCO 3, or Al 2 O 3, the reaction did not proceed, which suggests that piezoelectric materials are essential for this arylation reaction. We found that conducting the reaction at higher ball-milling frequency (30 Hz) substantially improved the yield (81%).
