金属氧化物纳米晶体的表面结构控制及功能调控的研究进展

摘要

Anisotropy is a basic property of crystals. Various facets or surfaces have different atomic structures and dangling bonds etc. ,which may result in different physical/chemical properties. Therefore,some physical/chemical properties of the crystals (especially for nano-crystals) can be tuned by controlling exposed crystal planes. Recently, controls of the surface structure of nanoparticles have been becoming a hot research topic in the field of chemistry and material science. In this article , we firstly make a brief overview of research achievements in the world in this field. Then, we focused on the recent research progress about the control of exposed nano-crystal facets with high surface energy of several functional metal oxides.%晶体具有各向异性,不同晶面上的原子排布、成键方式等都不尽相同,从而导致各种晶面的物理和化学性质的差异,因此通过控制裸露晶面就可以调控晶态材料(特别是微纳米晶态材料)的相关性质.近年来,关于微纳米晶体的表面结构控制的研究已成为纳米材料的一个研究热点.在文中,首先简要回顾国际上在该领域研究的情况,然后着重介绍了在部分金属氧化物微纳米晶体的表面结构控制方面的相关研究进展.
