Monodisperse palladium nanocatalysts for dehydrocoupling of dimethylamineborane

Abstract

Over the last several decades, dimethylamine borane, which is one of the ammonia borane derivatives, has been attracting attention as one of the most effective solid hydrogen storage materials. Herein, the preparation and characterization of activated carbon supported palladium nanoparticles was reported as a highly efficient catalyst for dehydrogenation of dimethylamine borane under ambient conditions. The characterization of prepared nanomaterials was made by using some analytical methods such as XRD, XPS, TEM, HR-TEM. The prepared nanomaterials were observed in the range of 3.46–4.36 nm with an approximate mean diameter of 4 nm. The results of these analyses showed that the new palladium nanoparticles were colloidally stable and crystalline. The catalytic activity and durability of prepared nanomaterials were investigated for the dehydrogenation of dimethylamine borane. The one of the best TOF (100.3 h−1) value was obtained for the dehydrogenation of dimethylamine borane. The investigations showed that the palladium nanoparticles have very high catalytic activity and stability at room conditions.
