In the study, activated carbon (AC) supported palladium/cobalt (Pd/Co) nanocatalyst was synthesized to achieve hydrogen release from dimethylamine boron (DMAB). Nanocatalyst were produced by the reduction of Pd 2+ and co 2+ cations by the ultrasonic double reduction method. Analytical studies of the synthesized nanomaterials were characterized by X-ray photoelectron spectroscopy, Raman spectroscopy, X-ray diffraction, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), electron energy loss spectroscopy, ultraviolet-visible spectroscopy. In this research, nanomaterials exhibited high catalytic activity and reusability, and great performance at low temperatures and concentrations. For the dehydrogenation reaction of dimethylamine borane, TOF and Ea were calculated as 379.5 h −1 and 75.86 kJ mol −1 , respectively. The PdCo@AC nanocatalyst can be used as a promising catalyst for the hydrogen production reaction from DMAB. Energy is considered a component of all activities and plays an important role in the economic development of any country. Increasing energy demand of the end users, one of the biggest problems of today, have been led researchers to investigate alternative, renewable and clean energy sources for energy supplying and storage. The use of hydrogen in countries with high energy dependence is widely involved in research and development. The hydrogen energy system is the best energy system expected to replace the fossil fuel system before the end of the twenty-first century. Hydrogen; in the next decades, is expected to become widespread use as an energy carrier for the supply of cheap electricity generation. However, easy production and improvement of storage are key points of the hydrogen economy for being safe, efficient and economical. Hydrogen energy is a high quality, non-polluting and, environmentally friendly. The state of art in the hydrogen economy are large and impressive. The creation of a worldwide energy network is essential for safe, economical transport 1-4. To date, metal complexes, metallic alloys, metal-organic frames (MOFs), and carbon materials have been studied as hydrogen storage materials. Metals such as Pd, Ru, Pt, Rh have been investigated for hydrogen storage. Since Pd can absorb a thousand times its own volume of hydrogen at ambient temperature and pressure, it is one of the leading hydrogen storage material. Therefore, research on Pd hydride (Pd-H) has been extensively studied in various fields, including hydrogen storage materials, purification filters, isotope separation membranes, and sensors. Such metals show high performance for hydrogen storage 5,6. However, its high-cost is big a disadvantage. In order to reduce the cost, studies have been performed with low-cost metal nanocatalysts such as nickel (Ni), copper (Cu), iron (Fe), and cobalt (Co). When cost effective metals are used alone, catalyst showed low performance and reusability 7-9. For this reason, it is aimed to synthesize both high activity and relatively cost effec...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
