| description | The invention provides a solid-in-liquid composite adsorbent for carbon dioxide capture and a preparation method and application thereof, and particularly relates to the technical field of carbon dioxide capture materials. The solid-in-liquid composite adsorbent comprises a shell and an inner core, the shell is prepared from hydrophobic SiO2 and hydrophobic modified biochar; the inner core is acid gas absorption liquid. By utilizing a unique solid-in-liquid structure, high specific surface area and low corrosivity of a solid adsorbent and high adsorption capacity and high selectivity of acid gas absorption liquid are combined, so that the adsorption capacity of the adsorbent is improved; the hydrophobic solid particle shell is used for wrapping the inner core of the acid gas absorption liquid, so that the contact area between the acid gas absorption liquid and trapping equipment is reduced, and the corrosion of the acid gas absorption liquid to the equipment is avoided. According to the embodiment, the CO2 ad |
