Increasing CO₂ emission from fossil fuel combustion in power production plants is the main reason to global warming. Carbon capture and storage technology (CCS) is promising method to reduce CO₂ emission. The cost of carbon capture accounts for most of the total cost of CCS technology, it is necessary to reduce carbon capture cost by enhancing capacity of the sorbent. Hydrotalcite is one of the promising sorbents that can capture CO₂ at the temperature range of flue gas from power plant. It is important to increase CO₂ sorption capacity of hydrotalcite for application to actual process. Increasing basic site of the sorbent can contribute to enhancing carbon capture capacity. This research used iron precursor for hydrotalcite synthesis in order to increase chemisorption site. The textural properties and pore volume were analyzed using N₂ adsorption analysis. Also varying the ratio of magnesium and iron precursor, the research optimize synthesis condition for high CO₂ sorption uptake.
