“…17 Specifically, SA is a porous material with a highly ordered 3D network structure composed of interconnected nanoscale silica particles. The unique "pearl chain" 3D network architecture confers SA with exceptional properties, 18 including an extremely high specific surface area, an exceptionally low thermal conductivity, and an extraordinarily high porosity. 19 As a result of these remarkable characteristics, SA is widely used in the fields of thermal insulation, 20 catalysis, 21 CO 2 adsorption, 22 and other related areas.…”

The significant accumulation of fly ash has resulted in serious environmental issues. It is imperative to find a safe and high-value method for reusing fly ash to effectively address this problem. Additionally, silica aerogels have gained attention as a promising material for energy conservation and thermal management. However, producing a silica aerogel with low production costs and superior overall properties is still a major challenge. In this study, silica−chitosan composite aerogels (SCA) were prepared from fly ash and chitosan. Amorphous silica is polymerized in situ on chitosan by hydrogen bonding and silyloxygen condensation. The resulting aerogels exhibited a fully formed block structure, extremely low density, exceptional flame retardancy, and notable mechanical properties (able to withstand 24,000 times the stress of its own mass). It is noteworthy that the nanopores and three-dimensional network structure endow SCA with excellent thermal insulation performance (with a thermal conductivity of 0.0474−0.0521 W m −1 K −1 ). The strategy presented here provides a cost-effective and straightforward approach to prepare SCA. The results demonstrate its considerable potential for practical use in energy-efficient and thermally insulated structures. Moreover, this approach offers a direct and high value-added solution to the problem of fly ash.

Transparent silica aerogel, serving as one typical porous and transparent material, possesses various unique features (e.g., large amounts of pores and interfaces, super‐lightweight, super thermal insulation, low refractive index similar to gas), and it has attracted great attention in the fields of science, technology, engineering, art, and others. Transparency is one important evaluation index of transparent silica aerogel, and it was influenced by various factors such as raw materials, sol‐gel reactions, phase separation, and drying methods. The structure design and fabrication of transparent silica aerogel is one huge and fine engineering. In this review, the optical/chemical guidance and design for the preparation of transparent silica aerogels are discussed, and typical applications, such as Cherenkov detectors, solar energy collection, lighting systems, and transparent fabric, also were discussed. Finally, a future outlook on the opportunities and challenges of transparent silica aerogels was proposed.
