Atmospheric concentrations of CO2, a major cause of global warming, have been rising due to industrial development. Carbon capture and utilization, which has been introduced to cover such disadvantages, makes it possible to capture CO2, recycling byproducts as resources. However, CCU also requires large amounts of energy in order to induce reactions. Among existing CCU technologies, the process for converting CO2 into CaCO3 requires high temperature and high pressure as reaction conditions. This study proposes a method to fixate CaCO3 stably by using relatively less energy than existing methods. Following the experiment, the resulting product CaCO3 was analyzed with FT-IR; FE-SEM image and XRD patterns were also analyzed. The results showed that the CaCO3 crystal product was high-purity calcite.
