“…Apart from using pure MOFs for electrochemical applications, considerable researches using MOFs as sacrificial templates to obtain highly controlled porous nanostructured materials have been reported in recent years [56]. Owing to their advantages, such as high surface area and large pore volume, the MOF-derived carbon nanostructures by direct pyrolysis process have been demonstrated as a promising strategy to enhance their practical application at the industrial scale [10]. Since the first MOFderived carbon materials with high specifical surface area and outstanding electrochemical performance were reported by Xu et al in 2008, a number of MOF-based carbon materials with unique nanostructures have been reported.…”

“…Since the first MOFderived carbon materials with high specifical surface area and outstanding electrochemical performance were reported by Xu et al in 2008, a number of MOF-based carbon materials with unique nanostructures have been reported. In particular, ZIFs were widely used as precursors to fabricate nanoporous N-doping carbons due to their rich nitrogen content and exceptional thermal and chemical stability [10]. For example, Yamauchi et al [177] fabricated nanoporous carbons through direct pyrolysis of a commercial ZIF-8.…”

“…where A refers to the valid surface area of the porous electrode, ε corresponds to the dielectric constant of the used electrolyte, and d is the valid thickness of the EDL [10]. The ideal carbon electrode material requires high conductivity for electron transport, high surface area for effective electrolyte ion adsorption/desorption, and suitable pore diameter for rapid access and diffusion of electrolyte ions [11].…”

Due to the high specific surface area, high chemical stability and good characteristics of electrical and thermal conductivity, hollow-structured materials have attracted extensive research interest as electrode materials for energy storage applications. The high specific surface area of hollowstructured materials provides a high contact area with electrolyte, facilitating the rapid diffusion and transport of electrolyte ions. The walls of electrode materials in hollow structures are relatively thin, providing short electron/ion diffusion length. Besides, the voids in hollow structures are beneficial for accommodating the volume expansion of the anode materials in lithium-ion batteries. Thus the specific capacity and cycling stability of the energy storage devices is enhanced with increased utilization of the electrode materials. However, it still remains challenging on maintaining the stability of the delicate hollow structure during cycling. Developing a facile strategy for the largescale synthesis of hollow-structured electrode materials is worth studying as well.The aims of this project include the design and synthesis of transition metal oxides hollow microspheres for lithium-ion battery application and highly porous carbon microspheres for supercapacitor and aluminum ion battery applications. In the aspect of transition metal oxides, double-shelled polypyrrole-zinc ferrite hollow microspheres will be fabricated and its electrochemical properties will be investigated. In the other aspect of highly porous carbon, nitrogen-doped mesopore-dominated carbon microspheres will be synthesized and its electrochemical properties will be investigated. Nitrogen-doped macroporous carbon microspheres will be fabricated and its structural parameters will be investigated. The specific achievements obtained in this thesis are listed as follows:Nanocompositing is known as a promising approach for the structural stabilization of the preformed hollow structures. In the first part, ZnFe 2 O 4 double-shell hollow microspheres are synthesized for the accommodation of the large volume expansion during lithiation. A facile and efficient vaporphase polymerization method is developed to coat the ZnFe 2 O 4 hollow spheres with polypyrrole.The thin polypyrrole coating improves not only the electronic conductivity but also the structural integrity of the ZnFe 2 O 4 hollow spheres. When evaluated as the anode in lithium-ion batteries, the polypyrrole coated ZnFe 2 O 4 hollow spheres manifest significantly improved cycling stability and rate capability than the pristine ZnFe 2 O 4 hollow spheres.Apart from transition metal oxide hollow spheres that used as anode in lithium-ion batteries, highly porous carbon materials show great potential on supercapacitors and other energy storage devices.Thus, in the second part, we develop a novel "spray drying-vapour deposition" method for the synthesis of the N-doped mesoporous carbon microspheres, in which, commercial Ludox silica nanoparticles are used as porogens for the surfactant-free sy...
