| 中文摘要: |
| 过渡金属氧化物Co3O4的晶体结构及表面特性与其形貌尺寸微观结构密切相关。本文将不同形貌Co3O4纳米材料按尺寸分为：纳米球、立方块、多面体的0D；纳米线、纳米棒、纳米管、纳米柱等的1D材料；纳米片、纳米薄膜等的2D；海胆状、微米球等由纳米单元构成的微米尺寸3D超结构。并探讨了对形貌形成的影响因素,重点研究其水热合成过程,总结了可能的形成机理,以利于对不同维度材料的形成规律有较深入的理解,进而能在理论上指导特定维度、特定形貌材料的可控合成。 |
| 英文摘要: |
| Crystal structure and surface characteristics of transition metal oxide Co3O4 are closely related to its morphology, size and microstructure. In this paper, different morphology Co3O4 nanomaterial could be divided into several dimensions through scale, including 0D of nanospheres, cubes, polyhedral, etc; 1D of nanowires, nanorods, nanotubes, nanocolumns and others; 2D of nanometer film, etcicron ball, etc and 3D of microscale superstructure constituted by nano-element such as urchin, micron ball etc. we discussed the influencing factors in formation of morphology, focused on the hydrothermal synthesis process and summarized the possible mechanism, to facilitate the deeply understanding of preparation of different dimension materials. Accordingly, it would provide a guidance for the synthesis of materials with specific dimension and morphology. |
