Abstract:

To briefly summarize the work reported in this PhD thesis, we can say that the study of the solvothermal synthesis of MnO NPs led to procedures to obtain anisotropic MnO NPs starting from manganese(II) oleate and stearate. A detailed investigation on the influence of the reaction conditions on the size, shape, crystal structure and magnetic properties of the obtained nanoparticles was carried out, including a detailed comparison between the two precursors (manganese oleate and manganese stearate) and surfactants (oleic acid and stearic acid) and a thorough investigation of the influence of the

To improve the reversible capacity, cycling stability, and electrochemical performance of CMK-8 based anodes for applications in LIBs, two types of metal oxides such as NiO (theoretical capacity = 718 mA h g-1) and Mn3O4 (theoretical capacity = 937 mA h g-1) were chosen to embed into the mesopores of CMK-8 separately in this study.
