USING ION BEAM IRRADIATION METHOD TO CHANGE THE ATOMIC STRUCTURES OF MATERIALS TO ENHANCE THEIR ABILITY TO TRAP CARBON DIOXIDE

The reduction of atmospheric CO2 requires thought-provoking ideas that would help reduce the concentration level in the atmosphere. In this study, the authors suggest the atomic modification of zeolite materials through controlled electron and ion beam damage to increase their carbon capture capacities. Zeolite samples were synthesized by hydrothermal method and subsequently, two different types of electron beam irradiation were performed on the samples. In the inert gas medium, zeolite samples were irradiated to restrict the structural degradation. In contrast, the vacuum medium which had a raster magnet was the other type which allowed a wide dispersion of the electron beam. The absorbed keratins ranged from 500 kGy to 1000 kGy, and the progression encouraged structural changes in the zeolites to increase the CO₂ adsorption uptake. The results have shown that lewis acid zeolite shows increased uptake of CO2 forming an exceptionally high adsorbed volume of 87.86 cm³/g at 500 kGy. The generation of modified zeolites has made it possible to use the innovative Carbfix technique which incorporates the dissolved CO² in water and then pumps it into the basalt layers and harnesses the natural occurrence of minerals to fix the CO2. The methods of modified samples were examined by PXRD, FE-TEM and FE-SEM techniques, TGA and spectrometric methods.
