Pd/BP2000 Nanocomposites: Efficient Catalyst for Hydrolytic Dehydrogenation of Ammonia-borane

Abstract

In current work, the activity of BP2000 supported Pd nanoparticles (NPs) were researched based on hydrolysis of ammonia borane (AB) reaction. Borane-tert-butylamine used for reduction of palladium (II) acetylacetonate for synthesize procedure of Pd NPs under mild conditions. As prepared Pd NPs were assembled on the BP2000, by liquid-phase self-assembly method. X-ray diffraction (XRD), transmission electron microscopy (TEM) and inductively coupled plasma-mass spectroscopy (ICP-MS) -advanced analytical techniques- were performed for detailed characterization. BP2000-supported Pd NPs were exhibited excellent activity and stability for the hydrolysis of AB. Pd/BP2000 nanocatalyst were showed the enhance catalytic activity that calculated turnover frequency (TOF) of 20.4 min−1. The detailed report clarified the kinetics of Pd/BP2000 nanocatalyst parameters on catalyst amount, AB concentration, temperature and reusability. After the hydrolysis of AB with Pd/BP2000 nanocatalyst, activation energy of reaction was calculated to be 41.5 kJ mol−1.
