[资源] Formation of Nanotubes and Hollow Nanoparticles

Formation of Nanotubes and Hollow Nanoparticles Based on Kirkendall and Diffusion Processes: A Review
2007Small最新一期关于Nanotubes and Hollow Nanoparticles 的综述：

The Kirkendall effect is a consequence of the different diffusivities of atoms
in a diffusion couple causing a supersaturation of lattice vacancies.This
supersaturation may lead to a condensation of extra vacancies in the form of
so-called “Kirkendall voids” close to the interface.On the macroscopic and
micrometer scale these Kirkendall voids are generally considered as a
nuisance because they deteriorate the properties of the interface.In contrast,in the nanoworld the Kirkendall effect has been positively used as a newfabrication route to designed hollow nano-objects.In this Review we
summarize and discuss the demonstrated examples of hollow nanoparticles
and nanotubes induced by the Kirkendall effect.Merits of this route are
compared with other general methods for nanotube fabrication.Theories of
the kinetics and thermodynamics are also reviewed and evaluated in terms of
their relevance to experiments.Moreove r, nanotube fabrication by solid-state
reactions and non-Kirkendall type diffusion processes are covered.
