High-energy ball milling, mechano catalysis, porous polymeres
The synthesis of organic and inorganic compounds can often be simplified with mechanical activation. Solvents are not necessary, the reaction time is often reduced and completely unknown compounds can be synthesized. Reactions under gas pressure (up to 300 bar) can de done directly in a ball mill with in-situ observation of the reaction conditions by a telemetric data logging system.
The picture shows the evolution of the hydrogen pressure and the temperature during the hydrogenation of Ti-doped NaAlH4. Our intention is the development of new synthetic procedures through mechanical activation.
