Cellulose-based materials for carbon capture and conversion

With the worldwide attention on decreasing carbon dioxide (CO2) emissions, carbon capture and storage (CCS) is utilized to stop CO2 from escaping into the atmosphere. Selecting appropriate materials is crucial for the establishment of a dependable and secure carbon capture and storage technology infrastructure. The natural cellulose materials possess inherent characteristics such as eco-friendliness, high utility, remarkable physical and mechanical properties, which make them particularly available for CCS. In the field of carbon capture, utilization and sequestration technologies, cellulose-based materials can be used as adsorbents for CO2 capture and as catalyst carriers for CO2 conversion. Firstly, the application of cellulose-based materials in carbon capture and conversion is introduced. Secondly, the research progress of cellulose-based films, aerogels and solid adsorbents in the field of carbon capture are summarized. Subsequently, the research mechanisms of cellulose-based materials for the conversion of CO2 to methanol format, carbonate and CO are also described in detail. Finally, the challenges and the key problems of cellulose-based materials in carbon capture and utilization are described.
