| Achoimre: | Title screen The issues of decarbonization, which have recently received increased attention from the world community mainly in connection with global warming, require the search for new solutions related to the utilization of carbon dioxide. The main problem of carbon dioxide conversion is the need to overcome the high stability of its molecules, which requires the supply of a substantial amount of energy. This study describes experimental results on the high energy plasma dynamic synthesis of metal oxides in a carbon dioxide medium using the Ti–O and Fe–O systems as an example. Nano- and micropowders of iron and titanium oxides are obtained by utilizing CO2 in a sectioned capacitive energy storage device with a coaxial magnetoplasma accelerator with titanium and steel electrodes, which are the main components of the plasma dynamic synthesis system. The powders are synthesized using plasma chemical reactions that occur during high-speed sputtering of a carbon electric discharge plasma into the atmosphere of a reactor chamber filled with carbon dioxide. The possibility of controlling the volume of CO2 utilized in the synthesis process by changing the type of electrodes and the number of successive power supply pulses is shown. It is established that up to 15 vol % of CO2 can be utilized to obtain up to ~9 g of dispersed products when using titanium electrodes and a multipulse operating mode in the considered system. It should be noted that the formation of classical rutile and anatase phases, as well as Magnéli phases and titanium carbide without traces of pure metal, is observed when titanium electric discharge plasma is sputtered in a CO2 medium. This indicates that the plasma dynamic synthesis makes it possible not only to utilize carbon dioxide but also to obtain useful powder products that can later be used as feedstock for various applications Текстовый файл AM_Agreement |
