本文研究了水热条件下SnO_2纳米晶体在钛酸钠纤维表面的吸附生长特性.采用水热法,以钛酸钠晶体纤维和适量的SnCl_4· 5H_2O为前驱物,水热反应条件为pH值11,填充度68%,反应温度120 ℃、150 ℃,反应时间24 h,在钛酸钠纤维表面生长了金红石相SnO_2纳米晶体,晶体尺度约为5 nm.实验结果显示钛酸钠晶体表面具有很强的表面活化能.
In this paper, the adsorption growth characteristics of SnO_2 nanocrystals grown on the surface of sodium titanate crystal fibers were investigatived. The rutile structure SnO_2 nano-crystals quantum dot have been prepared on the surface of sodium titanate crystal fibers by the hydrothermal method using sodium titanate crystal fibers and proper amount of SnCl_4· 5H_2O as the precursors. The reaction conditions was pH value 11, the fill factor was 68%, reacting temperature were 120 ℃ and 150 ℃ respectively, the total reacting time was 24 h. The SnO_2 nano-crystals had a size of about 5 nm. The results show that the surface of sodium titanate had a strong apparent activation energy.
