Layered Double Hydroxides: Porous Hybrid Network of Graphene and Metal Oxide Nanosheets as Useful Matrix for Improving the Electrode Performance of Layered Double Hydroxides (Small 32/2015)

The porous structure of a Co-Al-LDH–graphene–layered MnO2 nanohybrid is compared with the agglomerated structure of MnO2-free-Co-Al–LDH–graphene by S.-J. Hwang and co-workers. On page 3921, the Co-Al-LDH–graphene–layered MnO2 nanohybrid shows a porous morphology formed by the house-of-cards-type stacking of sheet-like crystallites. The incorporation of the MnO2 nanosheets provides more sites for the intercalation of potassium ions and also creates more open sites by preventing the agglomeration of rGO nanosheets.
