摘要: Nanocrystalline hexaaluminate-type mixed oxides having crystallite sizes of around 20 nm and high surface areas (>77 m2 g−1) were synthesized using an original mechanosynthesis technique. These nanocrystalline materials evidenced to be highly active heterogeneous catalysts compared the conventional parent materials.
