Tailoring Aerogels and Related 3D Macroporous Monoliths for Interfacial Solar Vapor Generation

Interfacial solar vapor generation is emerging as a promising water treatment technology with high solar energy efficiency and minimized carbon footprint. Among various kinds of materials development, aerogels, with inherent high porosity, lightweight, enhanced absorption, and minimized thermal conductivity, are attracting significant attention for achieving high-performance solar vapor generation. Herein, recent progress in tailoring aerogels (such as graphene [oxide], carbon nanotubes, and polymer aerogels) and related 3D macroporous architectures for interfacial solar vapor generation is presented. Furthermore, the challenges and opportunities associated with employing aerogels in solar vapor generation are also discussed.
