Abstract: A method for preparing a nano carbon dioxide agent and an application of the agent are disclosed. The method takes cationic surfactant modified bentonite as a carrier, and the CO2 nano agent prepared by loading cationic surfactant modified chitosan, graphene oxide and organic alkali modified hydrotalcite has the photocatalytic effect of nano materials, which can enhance photosynthesis, increase photosynthetic rate, inhibit light respiration at night, synthesize chlorophyll for crop growth, accumulate three essential elements of carbon, hydrogen and oxygen for crop growth, effectively absorb, synthesize and transform organic components such as nitrogen, phosphorus and potassium in soil, fully promote the gestation, growth and maturity of crops, and increases production and income. The CO2 capture agent of the disclosure can be used for both facility crops and field crops, and the CO2 capture agent under normal temperature and pressure has wide application.
