High Surface Area “3D Graphene Oxide” for Enhanced Sorption of Radionuclides

Here preparation of high surface area activated reduced graphene oxide (arGO) oxidized into a 3D analogue defect-rich GO (dGO) is reported. Surface oxidation arGO results in carbon to oxygen ratio C/O = 3.3, similar the state while preserving BET about 880 m2 g?1. Analysis shows abundance functional groups which converts hydrophobic precursor hydrophilic material. High carbons provide whole for without need intercalation and lattice expansion. Therefore, methods are sufficient convert materials architectures with chemical properties oxide. The “3D oxide” sorption capacity U(VI) removal an extraordinary broad interval pH. Notably, material has rigid structure micropores accessible penetration radionuclide ions. bulk GO” can be used as sorbent directly dispersing, step required make its pollutants.
