好久没有在催化版发帖了，好久没有收到金币奖励了，今天课题需要查了些文献，发现这篇文献可能还值得一读，故推荐给大家，随便赚几个金币花花！

Oxygen vacancies in transition metal and rare earth oxides: Current state of understanding and remaining challenges

M. Ver´onica Ganduglia-Pirovano, Alexander Hofmann, Joachim Sauer Humboldt-Universit¨at zu Berlin, Institut f¨ur Chemie, Unter den Linden 6, D-10099 Berlin, Germany Accepted 26 March 2007

Abstract
Defects at transition metal (TM) and rare earth (RE) oxide surfaces, neutral oxygen vacancies in particular, play a major role in a variety of technological applications. This is the motivation of numerous studies of partially reduced oxide surfaces. We review, discuss, and compare theoretical data for structural and electronic properties and energetic quantities related to the formation of oxygen defects at TM and RE oxide surfaces using TiO2, ZrO2, V2O5, and CeO2 as examples. Bulk defects, as far as relevant for comparison with the properties of reduced surfaces, are briefly reviewed. Special attention is given to the fate of the electrons left in the system upon vacancy formation and the ability of state-of-theart quantum-mechanical methods to provide reliable energies and an accurate description of the electronic structure of the partially reduced oxide systems.
