University of Technology, Tianjin 300384, China 10.3762/bjnano.9.168 Abstract Novel hexagonalnanoplates (NPLs) comprised of mesoporous carbon containing imbedded magnetic Co nanoparticles (CoAl2O4 phase) are prepared through direct carbonization of polydopamine (PDA)-coated CoAl layered double hydroxide

Nanocomposites with unique electronic, mechanical, magnetic, and physicochemical properties have gained much attention because of their large specific surface
composite materials are expected to show excellent performance in the preparation of TM-MCNs.
Here we report a facile approach for the preparation of novel hexagonalnanoplates (NPLs) containing magnetic Co nanoparticles (in CoAl2O4 phase) and porous carbon by carbonizing PDA-coated CoAl LDH, which can be

so that triangular and hexagonalnanoplates with narrow size distribution form. Width and thicknesses of the nanoplates were controlled by changing the PVP concentration: An increasing PVP concentration decreased the number of nuclei and resulted in larger plates, while the absence of PVP led to
