The origin of bio-based aerogels is from
sustainable resources, and their peculiar features, as well as their
preparation technique, form the most fascinating aerogels with CO2
capture applicability. Using diverse polysaccharides and proteins to
make biobased aerogels is a safe, cost-effective, and ecologically
beneficial way. Polysaccharides, found in nature are biodegradable
and renewable. A new generation of biomass-based aerogels was
developed in the twenty-first century. These materials are known as
bio-aerogels, and preparation techniques for producing bio-based
aerogels generally begin via combining the substances required,
followed by processes that involve gel formation, and the most
important is the removal of solvents from the moistened gels. In
this review, we have examined the preparation of bio-based aerogels,
sustainability, and their applicability in CO2 capture. |
