Abstract
Aerogels have a wide range of uses because of their extraordinary properties, which include a high specific surface area, enormous porosity, low bulk density, great thermal stability, and nanoscale particle size. TiO2 aerogels are viewed as having potential for solving environmental and energy issues by being employed in photocatalysis because many researchers believe TiO2 to be an environmentally friendly substance. TiO2-based hybrid aerogels have attracted significant attention currently because to their remarkable effective for photocatalytic degradation of organic dyes in wastewater treatment. These aerogels combine aerogels’ large surface area, porosity, and light scattering qualities with TiO2’s photocatalytic activity, allowing for rapid and effective dye degradation under UV or visible light. The use of hybrid components such as graphene oxide, SiO2, or polymers improves charge separation, light absorption, and recyclability. Recent developments have shown that the most advantageous and promising innovative material for photocatalytic dye degradation applications is TiO2-based hybrid aerogels. This in-depth analysis presents the most recent research on TiO2-based hybrid aerogels, covering common manufacturing techniques and their use in photocatalytic dye degradation. This review is intended to spark multidisciplinary research interest in rationally using hybrid aerogels based on TiO2 to create more effective photocatalysts for real-world use. TiO2-based hybrid aerogels have the potential for sustainable and scalable environmental clean-up, solving key difficulties in water pollution control.
