AI Technical Summary
Existing composite materials of carbon quantum dots and carbon nanotube aerogels are unstable at the interface and have uneven distribution of functional components, resulting in poor structural stability and performance consistency. In particular, the regeneration efficiency decreases when recycled in complex environments.
Carbon quantum dot-supported carbon nanotube aerogels were prepared by photo-induced method. Polyvinyl alcohol was used as a dispersant and network reinforcing component. Combined with the hydrogen bonding of functional groups on the surface of carbon nanotubes and molecular chain entanglement, a stable three-dimensional framework was formed. The material was rapidly adsorbed and regenerated by photo-irradiation.
It improves the structural stability and interfacial bonding stability of the material, enhances its adsorption capacity for complex polluted oil samples, and achieves rapid regeneration through photothermal means, exhibiting good cycle stability.
