制备了锂蒙脱石（LHT）插层Pd[II]配合物催化剂[Pd（NH3）4]2+/LHT和[Pd（PDT）3]2+/LHT，并通过XRD和IR对其进行了表征。[Pd（NH3）4]2+/LHT和[Pd（PDT）3]2+/LHT在空气中的基底间距（d 001）分别为1.30 nm和2.21 nm。当插层催化剂用DMSO溶剂溶胀时，[Pd（NH3）4]2+/LHT的d 001变为1.45 nm，[Pd（PDT）3]2+/LHT的d 001变为2.94 nm。这两种类型的插层Pd[II]配合物催化剂用于在DMSO中的炔氢化，以研究间隙间距（对于LHT = d 001 - 0.96（nm））对其催化活性的影响。
Hectorite(LHT)-intercalated Pd[II] complex catalysts, [Pd(NH3)4]2+/LHT and [Pd(PDT)3]2+/LHT, were prepared and characterized by XRD and IR measurements. The basal spacings(d001) of [Pd(NH3)4]2+/LHT and [Pd(PDT)3]2+/LHT were 1.30 nm and 2.21 nm in air, respectively. When the intercalated catalysts were swelled with the DMSO solvent, d001became 1.45 nm for [Pd(NH3)4]2+/LHT and 2.94 nm for [Pd(PDT)3]2+/LHT. These two types of the intercalated Pd[II] complex catalysts were used for hydrogenation of alkynes in DMSO to study the effect of the clearance spacings(= d001− 0.96 (nm) for LHT) on their catalytic activities.
