Dimetilamin boranın dehidrojenlenmesinde aktif bir katalizör olarak metal nanoparçacıklar

Energy, which has an important place in human life, has become the most important need in developing countries as well as in developed countries. However, energy production and consumption started to be a criterion that determines the level of development of countries. The need for energy increases day by day in parallel with the increase in population and technological developments. Today, the majority of energy resources are fossil fuels. Depending on the reasons such as the gradual decrease in fossil fuel reserves, the continuous increase in prices, the negative effects on human health and the environment; There are renewable energy sources in the world and especially in developing countries. Of these renewable alternative energy sources, hydrogen is undoubtedly the fuel of the future. Although many methods are proposed for the production of hydrogen gas, hydrolysis of alkali metal hydrides is often preferred. The use of dimethylamine borane is quite common due to the high percentage of hydrogen (wt 17%) it contains. In the appropriate solvent and catalyst environment, all of the hydrogen contained in the dimethylamine borane can be released, and in these reactions transition metal-based catalysts are generally preferred. In this thesis, heterogeneous catalyst is preferred because of its high stability and reusability properties, and copper is used as transition metal because of low cost and high amount of nature. The effect of titanium dioxide on hydrogen production performance, which is used as support material in order to increase the surface area and prevent agglomeration, was investigated in the production of hydrogen from the dimethylamine borane. In addition, the preparation, characterization analyses and the experiments of the catalytic efficacy Cu(0) NPs loaded on the surface of TiO2 were investigated. Copper nanoparticles fixed on metal oxide UV-visible region electronic absorption spectroscopy (UV-Vis), transmission electron microscopy (TEM), Brunauer Emmett Teller (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (FT-IR).
