Efficient catalytic performance of Ru nanoparticles for hydrogen generation from NH3BH3: The dual role of Mo oxide

Ru nanoparticles doped and supported by Mo oxide (Ru/Mo oxide NPs) were synthesized via an in situ co-precipitation strategy for hydrogen production via hydrolysis of ammonia borane (AB). The optimized Ru 0.9 Mo 0.1 catalyst composition exhibited a total turnover frequency (TOF) value of 514.8 mol H2 (mol Ru0.9Mo0.1 ) −1  min −1 at room temperature. Systematic characterization of the catalysts unveiled the dual role of Mo oxide in regulating the structure and catalytic performance of Ru NPs. This work provides a new approach for the design of Ru-based nanocatalysts toward hydrolysis of AB for H 2 harvest.
