[求助] 求助ZnO溶胶的合成

Typically,
the desired metal salt (NiCl2, Zn(NO3)2, SnCl4) was dissolved in
ethanol (100 mL) and the solution was heated at 80 8C for 2 h.Tetramethylammonium hydroxide (TMAH) was added to adjust the pH value of
the final suspension to about 10. Then the mixture was stirred for 1 h at
room temperature. Afterwards, the mixture was exposed to high-intensity
ultrasonic irradiation (6 mm diameter Ti-horn, 300 W, 20 kHz) at room
temperature in ambient air for 30 min and an MO sol was obtained

我按照上述步骤制备氧化锌溶胶,Zn(NO3)2应该加多少,为什么要调节PH值,有没有很懂得大牛,给解释解释机理呗?

ZnO遇到酸性物质会水解,具体的添加量需要根据实际情况换算吧?
