一种壳聚糖插层与Al/Fe复合柱撑协同改性蒙脱土负载钯催化剂的制备方法
摘要：
本发明涉及一种用于有机偶联反应非均相催化的一种壳聚糖插层与Al/Fe复合柱撑协同改性蒙脱土负载钯催化剂的制备方法，属于催化剂材料制备工艺技术领域。本发明包括以下步骤：（1）Al/Fe复合柱撑液的制备；（2）Al/Fe复合柱撑蒙脱土的制备；（3）通过溶液插层与化学络合制备壳聚糖插层与Al/Fe复合柱撑协同改性蒙脱土负载钯催化剂。本发明的一种壳聚糖插层与Al/Fe复合柱撑协同改性蒙脱土负载钯催化剂的制备方法有效改善了单一采用有机高分子改性或无机柱撑改性蒙脱土在性能提升上的不足，制备的Pd@CS-Al/Fe-pillared MMT催化剂不仅有较高的比表面积和吸附性能，钯活性组分与载体的络合强度高，在有机偶联反应催化应用中表现出优异的综合性能。
摘要（英）：

The invention relates to a preparation method of a chitosan intercalation and Al/Fe composite pillared synergistically-modified montmorillonite supported palladium catalyst for heterogeneous catalysisof organic coupling reaction, and belongs to the technical field of catalyst material preparation technology. The preparation method comprises the following steps: (1) preparation of an Al/Fe composite pillared liquid; (2) preparation of Al/Fe composite pillared montmorillonite; and (3) preparation of the chitosan intercalation and Al/Fe composite pillared synergistically-modified montmorillonitesupported palladium catalyst by solution intercalation and chemical complexation. The preparation method of the chitosan intercalation and Al/Fe composite pillared synergistically-modified montmorillonite supported palladium catalyst effectively improves the defect of single organic polymer modified or inorganic pillared modified montmorillonite in performance improvement, and the prepared Pd @ CS-Al/Fe-pillared MMT catalyst not only has higher specific surface area and adsorption performance, but also has high complexing strength of palladium active components and carriers, and shows excellent comprehensive performance in catalytic application of organic coupling reactions.
