“…The observation of bulk metal precipitation at the end of the lifetime experiments suggests the deactivation to be because of agglomeration of nanoparticles. The initial apparent TOF values are comparable with the best heterogeneous catalyst and much higher than the majority of those of other heterogeneous and homogeneous catalysts reported up to now, such as Ru NPs/ZIF‐8, mer ‐[Ru(N 2 Me 4 ) 3 (acac)H], trans ‐[Ru(acac) 2 (OAm) 2 ], Pt 0 /OA@CNT, Pt 0 /DOA@CNT, and nanogel‐supported Ni particles (Table ).…”

Copper(0) nanoparticles, in situ generated from the reduction of copper(II) 2‐ethylhexanoate during the dehydrogenation of dimethylamine borane (DMAB) at 50.0±0.1 °C in toluene solution, are active catalysts in hydrogen generation from DMAB, but not very stable against agglomeration. Addition of 5.0 equivalents of oleylamine (OAm) was found to stabilize copper(0) nanoparticles noticeably, while maintaining high catalytic activity. Oleylamine‐stabilized copper(0) nanoparticles could be isolated from the solution and characterized by XRD, TEM, UV/Vis, attenuated total reflectance (ATR)‐FTIR, and 11B NMR spectroscopies. Our report also includes (i) comparative catalytic activities of copper(0) nanoparticles in the absence and presence of OAm depending on the initial [OAm]/[Cu] ratio, catalyst concentration, substrate concentration, and temperature, (ii) the catalytic lifetime of copper(0) nanoparticles in the absence and presence of OAm in the dehydrogenation of DMAB at 50.0±0.1 °C, (iii) testing the ease of isolation and reusability of copper(0) nanoparticles in the absence and presence of OAm in the dehydrogenation of DMAB, (iv) the results of quantitative kinetic poisoning experiments by using 1,10‐phenanthroline, showing that copper(0) nanoparticles are kinetically competent catalysts in the dehydrogenation of DMAB.

Highly monodisperse graphene oxide‐supported Ru/Pd nanoparticles (RuPd@GO NPs) have been reproducibly and easily synthesized by microwave assisted method. RuPd@GO NPs was performed for dehalogenation of arylhalides in the presence of ammonia borane in a mild condition as novel, highly efficient and exceptional reusable heterogeneous catalyst. The novel materials were characterized by transmission electron microscopy (TEM), the high resolution electron micrograph (HRTEM), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS). The results showed that the prepared catalysts are highly crystalline, monodisperse and colloidally stable. The current one‐pot catalytic process was described as a new methodology for dehalogenation of arylhalides which can be assessed as a quite simple, eco‐friendly and highly efficient as well as exceptional reusable. All products were provided with one of the highest yield and the shortest time in the presence of novel RuPd@GO NPs due to the the synergistic effect of Ru and Pd. Our synthesis process comes with a facile and eco‐friendly option to RuPd@GO NPs, allowing further scrutiny of current catalysts for numerous other chemical reactions.
