[Abstract]:Biomass is the most economical, environmentally friendly and sustainable raw material in the preparation of carbon aerogels because of its low cost and abundant carbon sources. Biomass based carbon aerogels have the advantages of low density, high elasticity, large specific surface area and good electrical conductivity. It is expected to be widely used in electrochemical energy storage devices and adsorption purification. The preparation process of biomass based carbon aerogels, such as cellulose carbon aerogels, lignin based carbon aerogels, biomass derivative carbon aerogels and carbon aerogel composite materials are reviewed. The application of biomass-based carbon aerogels in adsorption and electrochemistry was summarized. Finally, the opportunities and challenges of large-scale preparation of biomass based carbon aerogels with uniform structure and excellent performance were analyzed.
