Abstract: Five types of nanocarbon structures and hybrids have been developed in this project. Firstly, fluorescent carbon dots are synthesized by hydrothermal treatment of glucose in the presence of monopotassium phosphate. Secondly, by using glucosamine hydrochloride as the carbon precursor, nitrogen-doped carbon nanoparticles with intrinsically fluorescent behavior are established. Thirdly, hollow nanocarbon spheres are developed by hydrothermal treatment of a-cyclodextrin (a-CD) in the presence of poly (ethylene oxide)106-poly (propylene oxide)70-poly (ethylene oxide)106(F127) as the soft template. Fourthly, hollow nanocarbon spheres/manganese dioxide hybrids are formed by the redox reaction between carbon and permanganate. Finally, highly porous microspheres of graphitic carbon containing cobalt monoxide nanoparticles are successfully obtained by hydrothermal treatment of the mixture of cobalt gluconate, a-CD and F127. These five types of nanocarbon structures are investigated for their structures at varying lengthy scales and functional behavior for bioimaging and energy storage.
