【请教】请教乙酰乙酸乙酯的作用
|
||
|
The Ag/TiO2 powders were similarly prepared using a modified sol–gel method as described in our previous work [15]. In a typical synthesis, a 0.2 g solid AgNO3 was dissolved in 20 mL of ethanol, followed by addition of mixture containing 8 mL of tetra-n-butyl titanate, 80 mL of ethanol, 4 mL of ethyl acetoacetate. Then 1 mL distilled water was added by dropwise to the above mixed solution in the absence of light, the mixed solutionwas successively stirred for 4 h until a clear and transparent sol was obtained. Subsequently, the sol was dried at 353 K to get xerogel, which was grinded and calcined at 723 K for 2 h. 请问各位虫子，上边用到的ethyl acetoacetate（乙酰乙酸乙酯）起什么作用？是不是将银离子还原？ |
