Tunable assembly of porous three-dimensional graphene oxide-corn zein composites with strong mechanical properties for adsorption of rare earth elements

We have prepared several novel 3D GO-based porous composites, GOCZ materials, with strong compressive mechanical properties through a facile hydrothermal process by self-assembly of CZ and GO. The adsorption properties of 3D GOCZ composites for REEs were evaluated. Due to their excellent compressive properties, high desorption rates and reproducibility, the 3D GOCZ composites are expected to be used as recoverable adsorbents in the future.100
