Research Progress on the Preparation of Biodiesel Oil by Mixed Oxides from Hydrotalcite-like Compounds

水滑石类(Layered Double Hydroxides,LDHs)复合氧化物由于其独特的层状结构和离子可调变性广泛用于众多领域。本文综述了LDHs的结构特性以及其在催化制备生物柴油中的应用。对碱金属、碱土金属、过渡金属和稀土改性LDHs的催化活性、稳定性和可循环利用性进行了介绍,并对水滑石类复合氧化物的研究前景进行了展望。

Hydrotalcite-like compound, （named as layered double hydroxides, LDHs）. Because of its unique layered structure and flexible character of ion, LDHs has widely applied in many fields. In this review, the structural characteristics of LDHs and its application as catalyst in the preparation of biodiesel were summarized. The catalytic activity, stability and recycled of LDHs were introduced, which were modified by alkali metal, alkaline-earth metal, transition metal and rare earth application, then the research prospect of LDHs was discussed.
