Carbon dioxide is a carbon-oxygen compound, which is a colorless and odorless gas under normal temperature and pressure, soluble in water, and it is also a common greenhouse gas. Human survival cannot do without carbon dioxide, yet it is necessary to control its concentration in the air to address the impacts of global warming. Therefore, carbon dioxide capture agents have emerged, playing a crucial role in industrial applications for capturing carbon dioxide.

Carbon dioxide capture agents are characterized by easy regeneration, adsorption at room temperature, no loss of solid powder, and high adsorption efficiency. They are essential in industries with high carbon dioxide emissions, such as coal-fired power plants, waste incineration, smelting, glass manufacturing, fertilizer production, and cement plants.
