摘要

介绍了多相催化剂在制备U（Ⅳ）反应中的应用，着重探讨了不同催化剂在不同还原剂、不同酸性介质中还原U（Ⅵ）制备U（Ⅳ）的反应性能、反应过程及反应机理，最后提出催化还原U（Ⅵ）制备U（Ⅳ）值得深入研究的问题。

Abstract

Applications of heterogeneous catalysts in the preparation of U(Ⅳ) is introduced.The reaction performance, reaction process and reaction mechanism of different catalysts in the reduction of U(Ⅵ) to U(Ⅳ) in different reducing agents and acid media are discussed emphatically.The problems worthy of further study for catalytic reduction of U(Ⅵ) to U(Ⅳ) are put forward.
