本文介绍了一种具有明确结构的稳定的位置隔离的单核铂催化剂。以[Pt（NH3）（4）]（NO3）（2）为原料，合成了负载于KLTL沸石上的铂配合物，在633 K下氧化，并用于催化CO氧化。IR和X-射线吸收光谱和电子显微镜照片确定的结构和位置的铂络合物在沸石孔，证明铂支持键合，并表明，铂保持网站隔离后的氧化和催化。
A stable site-isolated mononuclear platinum catalyst with a well-defined structure is presented. Platinum complexes supported in zeolite KLTL were synthesized from [Pt(NH3)(4)](NO3)(2), oxidized at 633 K, and used to catalyze CO oxidation. IR and X-ray absorption spectra and electron micrographs determine the structures and locations of the platinum complexes in the zeolite pores, demonstrate the platinum-support bonding, and show that the platinum remained site isolated after oxidation and catalysis.
