▎ 摘  要

NOVELTY - Removing chromium ions (Cr(VI)) involves using graphitic carbon nitride nanosheets (g-C3N4)/cellulose/graphene oxide (GO) composite foam to catalyze the removal of Cr(VI) under visible light conditions. USE - Method for removing chromium ions. ADVANTAGE - The method uses foam, which is easy to recycle without complicated separation procedures, and CG-3 showed no significant loss of its original reduction performance after 9 cycles, and proves its high reusability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of g-C3N4/cellulose/GO composite foam, which involves taking urea as a precursor, and thermal polymerization obtains g-C3N4powder, dispersing into the mixed suspension of GO and cyanogen fluoride (CNF), freeze-forming, and then freeze-drying to obtain the g-C3N4/cellulose/GO composite foam.
