Carbon Dioxide Decomposition by Plasma Methods and Application of High Energy and High Density Plasmas in Material Processing and Nanostructures

The increase of carbon dioxide (CO₂) in the atmosphere can cause climatic and geographical changes which will destroy nature. In order to combat this destruction many researchers have attempted either decomposition of carbon dioxide or carbon dioxide sequestration so as to bring the carbon dioxide content down to 260 ppm in the atmosphere. In the present paper, we have summarized some of the earlier attempts at the decomposition of carbon dioxide. We give a detailed introduction about the gas tunnel type of plasma jet for the decomposition of carbon dioxide. However, in most of the earlier attempts, carbon dioxide decomposed into carbon monoxide which is highly poisonous and it is a drawback in these attempts. In order to circumvent this drawback we have proposed a scheme for decomposition of carbon dioxide using an array of high voltage electrode systems with which it may be possible to decompose carbon dioxide to its constituents. We will also present some of the results of material processing using the gas tunnel type plasma jet and high energy high density non equilibrium plasma under fusion conditions such as those prevailing in dense plasma focus (DPF) device
