Abstract
Bio-based aerogels with customizable porosities and functionalities constitute a significant potential for CO2 capture. Developing bio-based aerogels from different polysaccharides and proteins is a safe, economical, and environmentally sustainable approach. Polysaccharides are biodegradable, sustainable, renewable, and plentiful in nature. Because of these advantages, the use of bio-based aerogels with porosity and amine functionality has attracted considerable interest. In this review, we have discussed the recent development in the synthesis of bio-based aerogels and their application in CO2 capture.
Highlights
Bio-based aerogels are typically made from sustainable materials, like proteins, starch, sugar cane and vegetable oils etc
Bio-based aerogels are primarily synthesized by sol-gel and drying methods [13]
The hierarchical porous carbon aerogel derived by cellulose demonstrated a strong carbon dioxide adsorption potential of 3.42 mmol g-1, which suggests the probability of utilizing prepared material for CO2 adsorption
Summary
Bio-based aerogels are typically made from sustainable materials, like proteins, starch, sugar cane and vegetable oils etc. Biopolymers (like cellulose, alginate, chitosan, lignin, pectin, etc.) have been used effectively for bio-based aerogel preparation [1]. Thanks to their special properties, including biocompatibility, durability, low toxicity and renewability, bio-based aerogels can become the key component in novel functional materials and utilized for different applications (Figure 1)(2). Supercritical drying may preserve the structure of the gel and create products that have a higher surface region, smaller pore size and low shrinkage rate.
