Aerogels represent a class of materials with exceptional properties, including low density, high porosity, and ultra-low thermal conductivity, which have garnered significant interest across various fields, such as thermal insulation, photocatalysis, and protective applications. Despite their superior thermal attributes, aerogels face challenges such as fragility, high production costs, and handling difficulties. Recent studies have focused on enhancing aerogels' photocatalytic and insulating properties through composition optimization and microstructural reconstruction, leveraging their high surface area and porosity. Innovations in aerogel fabrication techniques, such as the grafting of vinyltrimethoxysilane onto polymethylhydrosiloxane chains, have led to the development of flexible, superhydrophobic aerogels with improved structural integrity and thermal stability. However, silica aerogels' fragility and moisture sensitivity continue to limit their widespread adoption, prompting research into hydrophobic, resilient aerogels capable of withstanding extreme temperatures and mechanical stress. The synthesis of polymer-reinforced SiO2 aerogels with enhanced flame resistance and mechanical properties has also been explored, although the thermal stability of organic components remains a concern. Similar is the case with carbon aerogels. This research landscape is ripe for further exploration to address these challenges and unlock the full potential of aerogels in industrial and technical applications.

This Research Topic aims to advance the understanding and development of aerogels, focusing on improving their mechanical strength, thermal stability, and cost-effectiveness while maintaining their unique insulating and photocatalytic properties. The goal is to explore innovative fabrication techniques, material compositions, and design variations that can overcome the inherent limitations of aerogels. By addressing these challenges, the research seeks to enhance the practicality and performance of aerogels in energy storage, thermal protection, and environmental applications, such as CO2 capture and oil-water separation.
