Özet

Herein, the authors report that TiO2 supported ruthenium nanoparticles (Ru(0)/TiO2) during hydrolysis starting with RuCl3/TiO2 precatalyst act as highly active, long-lived, and reusable nanocatalyst in the hydrogen generation from the hydrolysis of ammonia-borane (NH3BH3) at room temperature. The resulting Ru(0)/TiO2 catalyze hydrogen generation from the hydrolysis of ammonia-borane with an initial turnover frequency value of 200min(-1) at 25 +/- 0.1 degrees C. More importantly, Ru(0)/TiO2 are stable enough to be isolated and bottled as solid material, which can be reused as active catalyst under the identical conditions of the first run.
