Abstract

Superacid (H0 ≥ –14.52) ternary Zr35Si53Al12 and Zr21Si67Sn11 oxides have been studied by X-ray photoelectron spectroscopy. The high-energy shifts of Zr3d levels indicate the electron density shift from zirconium to silicon atoms, which is facilitated by the presence of tetrahedrally coordinated Al3+ and Sn4+ ions in Zr4+ environment. Models of the superacid L-sites that include coordinatively unsaturated zirconium ions are proposed.

ZrO2-SiO2-Al2O3和ZrO2-SiO2-SnO2三元氧化物表面的超酸性l -位
用x射线光电子能谱研究了超强酸(H0≥-14.52)三元Zr35Si53Al12和Zr21Si67Sn11氧化物。Zr3d能级的高能位移表明电子密度从锆原子向硅原子转移,这是由于Zr4+环境中四面体配位的Al3+和Sn4+离子的存在促进了电子密度的转移。提出了含配位不饱和锆离子的超酸性l位模型。
