Kirkendall效应和空心纳米晶体的人工合成

Kirkendall Effect and Synthetic of Hollow Nanocrystals

在1946年被发现的Kirkendall效应,对科学技术引起很大的冲击,至今,仍在许多科学技术和工程领域受到关注。本文悦目瞭然地阐述Kirkendall效应和Darken分析,计算实例,空位风和反Kirkendall效应。最后,更为重要地指明,2004年发表的应用纳米尺度Kirkendall效应人工合成中空纳米球方法提供了人工合成无机化合物的空心纳米晶体和纳米管的通用途径。近年来,这种具有空心结构的纳米晶体愈来愈受到人们的青睐。

The Kirkendall effect was discovered in 1946, nevertheless, it has given a great compact to many scientific and technological fields. Up to now, the Kirkendall effect have still been received a con- siderable number of regard to various fields in science and technologies. This paper clearly and minutely explains Kirkendall effect and Darken analysis, calculation example, vacancy wind and inverse Kirkendall effect. At the latest, it is shown particularly that the process of the formation of hollow nanocrystals through the nanoscale Kirkendall effect published in 2004 provides a general route to the synthesis of hollow nano- crystals and nanotubes of inorganic compounds. Currently, these nanocrystals with hollow nanostruetureare enjoyed growing favor for investigators.
