Ru(0)/TiIO2 nanokumleri esliginde dimetilamin boranin dehidrojenlenmesi

In recent years, global warming becomes life-threatening due to the increase in carbon dioxide levels in the atmosphere. Global warming has several effects that greatly harm the globe, the environment, and the climate and living organisms. Therefore, scientists have resorted to search alternative energy resources such as clean energy. In this regard, hydrogen is an energy carrier could be used as an alternative of other fuels. However, the safety storage of hydrogen is still key point. B-N compounds have high hydrogen capacity can be store hydrogen and release it under proper ambient conditions. One of the boron compounds is dimethylamine borane could be release hydrogen by suitable catalyst and reaction conditions. The main of the catalysts used in these types of reactions is agglomeration problems of them during the reaction course. Metal oxides are used as stabilizers in the production of transition-metal nanoparticles, which gives them benefits in terms of shelf life, reusability, and thermal stability. The ex-situ production, characterization, and catalytic performance of TiO2-supported ruthenium (0) nanoparticles in the dehydrogenation of DMAB at a temperature of 60.0 ± 0.5 °C are demonstrated in this thesis. Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and optical emission spectrometry were used to analyze transition metal nanoparticles (0) supported by metal oxides. Experiments with various catalyst concentrations and temperatures were performed to evaluate the reaction kinetics.
