Amorphous NiP/rGO for Hydrogen Generation from Hydrolysis of Ammonia Borane

The characterization results showed that rGO not only effectively prevented the agglomeration of NiP nanoparticles as a carrier, but also optimized the electronic structure of the catalyst through the electronic interaction between them.

In the ammonia borane hydrolysis reaction, this amorphous NiP/rGO catalyst exhibited excellent catalytic activity and stability, with an initial turnover frequency (TOF) of 21.93 min−1 and a low apparent activation energy (Ea ) of 17.86 kJ·mol−1 . Moreover, the cyclic stability test confirmed that the NiP/rGO catalyst remains excellent catalytic performance after 5 consecutive reaction cycles. This study provides a new idea for designing high-performance amorphous metal phosphide/carbon material composite catalysts, and shows good application prospects in the field of chemical hydrogen storage materials.
