| 摘 要： | 以NaHCO3为矿化剂采用溶剂热法合成了Zn2SnO4纳米粉体,通过X-射线衍射（XRD）、扫描电镜（SEM）和透射电镜（TEM）考察了矿化剂浓度、溶剂热反应温度和时间、表面活性剂等对样品组成、结构和形貌的影响,结果表明：矿化剂浓度较低时所得样品为SnO2,矿化剂浓度为1.0 mol/L、溶剂热反应温度和时间为200℃,24 h时,可得立方结构的分散均匀的Zn2SnO4纳米粉体,添加表面活性剂PVP后,样品粒度增大,立方块形貌更加明显. |

| Abstract: | Zn2SnO4 nanopowders have been prepared by solvothermal process using NaHCO3 as mineralizer. The effects of the concentration of NaHCO3, solvothermal temperature and time, surface active agent on the formation, structure, and morphology of products were investigated by X-ray diffraction, SEM and TEM. It was found that SnO2 was obtained when the concentration of NaHCO3 was low while cubic structure ZnaSnO4 nanopowders with perfect disperse could be obtained when the concentration of NaHCO3 was 1.0mol/L and solvothermal temperature and time was 200℃,24h. After PVP was added in solvothermal process, the size of sample increased and cubic morphology was more obvious. |
