乙酸钇水合物在 1,2-丙二醇 (1,2-PG) 中于 300°C 反应生成含有乙酸酯基团和二醇部分的产物。产物在400℃以下分解为Y2O3，所得Y2O3样品具有相当大的比表面积（>200m2/g），由外径7~18nm、内径2~8nm的结晶纳米空心球组成。通过糖热处理和随后的煅烧也获得了由纳米空心球组成的Dy2O3、Er2O3和Yb2O3。
The reaction of yttrium acetate hydrate in 1,2-propanediol (1,2-PG) at 300°C yielded the products containing the acetate groups and the glycol moieties. The products decomposed into Y2O3below 400°C, and the thus-obtained Y2O3samples had quite large surface areas (>200m2/g) and were comprised of crystalline nano-hollow spheres with the outer diameter of 7–18nm and the inner diameter of 2–8nm. Dy2O3, Er2O3and Yb2O3composed of nano-hollow spheres were also obtained by the glycothermal treatment and subsequent calcination.
