【摘要】 采用配体４ＣＨ３ＳＣ６Ｈ４ ＮＨ２ 插层的α磷酸锆（ＺｒＰ） 为插层主体，将Ｒｈ３ ＋ 引入层状材料的层板之间制备了新型层柱催化材料Ｚｒ（ＨＰＯ４）１ ．７０（ＣＨ３ＳＣ６ Ｈ４ＮＨ２）１ ．０９（ＰＯ４）０ ．３０ Ｒｈ０ ．１０·５－５２Ｈ２Ｏ，其层间距由２－３６ ｎｍ 变为１－５６ ｎｍ ， 结晶度有所下降． ＸＰＳ 结果表明，配体４ＣＨ３ＳＣ６Ｈ４ＮＨ２ 与Ｒｈ３ ＋ 之间形成了Ｎ→Ｒｈ 配位键，而没有形成Ｓ→Ｒｈ 配位键，Ｒｈ 的配合物与层板之间主要是静电作用． 配体在该层柱材料中的热稳定性比插入Ｒｈ３ ＋ 之前提高． 该层柱材料对甲醇羰基化反应具有较高的催化活性，羰基化选择性为１００ ％ ， 对乙酸甲酯具有较高的产物选择性．更多还原

【Abstract】 Pillared layered α zirconium phosphate (ZrP) material Zr(HPO 4) 1.70 (CH 3SC 6H 4NH 2) 1.09 (PO 4) 0.3 Rh 0.1 ·5 52H 2O has been prepared by intercalation of 4 (methylmercapto) aniline (MMA) and followed by Rh (Ⅲ) cations. XRD results show the interlayer distance of the material decreasing from 2 36 to 1 56 nm, and the crystallinity going down after the complex is formed in situ in the layers. XPS results show that the coordinate bond is formed between N from ligand MMA and Rh, The complexes have ionic interaction with ZrP layers. The thermal stability of MMA is enhanced after the intercalation of Rh cations. The pillared material has high activity in CH 3OH carbonylation and 100% selectivity for carbonylation.更多还原
