Graphene-based hybrid materials can be used in potential electrode materials, catalysts, biosensors, and methanol fuel cells. Graphene/Zn2+-Al3+ LDH materials may find an application in electroactive and photoactive materials, catalysts, flame retardants, acid absorbents, and anion exchangers. We have prepared hexagonal shape Zn2+-Al3+ LDH materials with high crystallinity by using urea as hydrolysis agent and trisodium citrate as complexing agent. In this research, a simple synthesis of hybrid graphene/Zn2+-Al3+ LDH materials has been fabricated by the hydrothermal treatment of a mixed suspension of exfoliated graphite oxide, Zn(NO3)26H2O, Al(NO3)3 9H2O, urea, and trisodium citrate. The exfoliated graphite oxide is simultaneously reduced to graphene in the homogeneous precipitation of Zn2+-Al3+ LDH. The composition, morphology, and thermal property of hybrid graphene/LDH materials were studied by SEM, TEM, XRD, XPS, TGA, DSC, and Raman. |
