摘要
综述了近年来以层状双金属氢氧化物(LDHs)为前躯体制备高分散催化剂的研究进展,基于LDHs层板金属阳离子以原子水平高度分散及层间阴离子以一定方式有序排布的结构特点,以LDHs材料作为单一前驱体,经层板剥离、晶格限域、插层组装及阵列化等途径制备催化活性位高度分散的多相催化材料具有显著的优势.
Layered double hydroxides（LDHs） refer to a class of clays with diverse brucite-like layers and intercalated anions,which have attracted increasing interest in the field of catalysis.Benefiting from the atomic-scale distribution of metal cations in the brucite-like layers and the ordered arrangement of diversified interlayer anions,the LDHs display great potential as the precursors to prepare catalysts in that the catalytic sites could be highly dispersed.The approaches to prepare catalysts from LDHs as precursors include,but not limited to,exfoliation of the brucite-like layers,confinement by the brucite-like layers,intercalation,and/or nanosheet arrays.The latest development of the catalyst preparation using LDHs as precursors was mainly summarized.
