▎ 摘　　要

Nanoparticle-based aerogels can combine the unique structures and properties from both nanoparticles and aerogels, and hence provide opportunities in a wide range of applications. The present liquid-dripping and liquid-extrusion methods to produce aerogels from nanoparticles have limited preparation efficiency and high condition requirements. Here, we report a new, highly efficient and robust liquid-granulating method to produce aerogel granules from nanoparticles and graphene oxide. The simple home-made set-up could produce 4 kg gel granules in 45 min, leading to an ever-high production efficiency and robustness. (C) 2020 Published by Elsevier B.V.
