摘要
催化技术在现代工业生产和日常生活中发挥着举足轻重的作用,开发高效的催化剂是催化领域重要的研究方向。近些年来,许多研究发现催化剂的缺陷对其催化活性有着重要的影响,同时各种各样的缺陷催化剂也被开发出来。尽管如此,缺陷与催化活性之间的关系仍有待厘清。本文围绕这一主题,分别介绍了固体缺陷化学的基础、催化剂中缺陷的类型、表征、可控构筑以及在催化中的作用和动态变化,最后进行总结和展望。希望通过本文阐明催化剂缺陷化学研究的起源与发展,强调缺陷对催化的重要性,为今后高效催化剂的进一步开发与机理研究提供指导。
Catalysis plays a significant role in modern industrial production and daily life and the exploration of efficient catalysts is an important issue of catalysis research.In recent decades,many researchers found the important effect of catalyst defects for their catalytic activity and various defective catalysts are prepared.Nevertheless,the relationship between defect and catalysis still needs clarification.In this review,we mainly introduce solid defect chemistry fundamental,defect types in catalysts,characterization and controllable construction of defects,the roles and the dynamic evolution of defects in catalysis.Finally,the summary and outlook for"defect with catalysis"are demonstrated.We hope this review can reveal the origin and development of catalyst defect chemistry,emphasize the importance of defect for catalysis and provide some guidance for exploration and mechanism researches of defect catalysts.
