Hierarchically structured nanomaterials have wide applications in catalysis, optics, life science etc., and are featured by structural complexity. Electron microscopy is an ideal method to investigate the hierarchical structure. The combination of imaging and spectroscopy techniques in electron microscopy provides us with the opportunities to study a broad class of hierarchically structured nanomaterials.

In this PhD work, electron microscopy is used to investigate the hierarchical structure, from micrometer level to atomic scale. The structure is linked to the synthesis and properties to reveal the relationship between them and to further optimize the synthesis approach. Due to the complexity of the hierarchical structures with hybrid composites, the examined materials in this PhD work are roughly organized in three groups as follows: Chapter II Silicon oxide based hierarchically structured nanomaterials, Chapter III Titanium oxide based hierarchically structured nanomaterials, and Chapter IV Zinc oxide based hierarchically structured nanomaterials. In the end, Chapter V presents the general conclusions and suggestions for future works.
