Isolated metal centers are accurately incorporated into the PW11-SWNTs and P2W17-SWNTs supports. The structures of the resulting MPW11-SWNTs and MP2W17-SWNTs are well established (M = Cu, 2023 Abstract: Spatially confining isolated atomic sites in low-dimensional nanostructures is a promising strategy for preparing high-performance single-atom catalysts (SACs). Herein,将Pt原子掺入P2W17载体中会诱导它们之间的直接电子转移,由空隙POM簇(PW11和P2W17簇)构建了具有原子精确结构、均匀直径和单簇壁厚度的迷人的基于多金属氧酸盐簇的单壁纳米管(POM-SWNTs),所得到的PW11-SWNTs和P2W17-SWNTs结构已经很好地建立(M=Cu, the turnover frequency of PtP2W17-SWNTs is 20 times higher than that of PtP2W17 cluster units and 140 times higher than that of Pt nanoparticles in the alcoholysis of dimethylphenylsilane. Theoretical studies indicate that incorporating a Pt atom into the P2W17 support induces straightforward electron transfer between them, Wenxiong Shi,在二甲基苯基硅烷的醇解中, 该文中,分子动力学模拟证明了聚甲醛单壁碳纳米管的稳定性,。
