[求助] 求解释

各位老师,小弟在一片文献上看到一个关于TiO2微球的合成方法
2.1. Synthesis of titania microspheres with hierarchical structures
0.25 mL of nonanoic acid was dropped into 20 mL of absolute
alcohol and 80 uL of 0.1 mol/L KCl aqueous solution was added. After
stirring for 15 min, 0.5 mL of tetra-n-butyl titanate was added under
violently stirring. 5 min later, 1 mL of double distilled water was
added. The milky white precursor microspheres suspension was kept
static for 24 h and collected by centrifugation.
The precursor microspheres were dispersed in an ethanol-aqueous
solution. Then the suspension was sealed within a Teflon-lined
autoclave (25 mL) and heated at 160 °C for 16 h. Following wash with
ethanol three times, the precipitate was dried at 40 °C. The
hydrothermal products were further calcined at 600 °C for 4 h to
obtain the targeted products.
想请问其中的KCl起的作用是什么?谢谢!!

在水热合成中加入卤素盐,通常是为了改善晶体生成的形貌颗粒大小,至于卤盐中的卤素怎么改善的,我忘了,好想和他具有较高的电负性有关。当然,这个很多文章都有解释,你可以去下载几篇看看
