[求助]
看有關(guān)七水合硫酸亞鐵還原硝酸銀制備納米銀的文獻(xiàn)是看到這里不懂,球大神指教!

| Once the two solutions are mixed, the nano Ag nuclei form, and the SO42− and the cations attach on the nano Ag nucleuses successively from the inner to the outer. So, the electrical double layers around the particles are formed in aqueous solutions. The thickness of the layers decreases with the increase of the ionic strength, which leads to the decrease of the range of the repulsion forces between the nano particles. |

first, nano-size primary particles are nucleated in a supersaturated solution, and then aggregate to form larger uniform secondary particles. In the initial stage, the aqueous solution becomes black due to the formation stabilizer of nano Ag particles, providing a “suitable” condition for the aggregation to form large grains in the aqueous solution. Thus, the color of solution turns yellow slowly with the continuous consumption of Ag+ and the growth of Ag particles. This is in good accordance with the kinetic model proposed by PRIVMAN et al[14] and PARK et al[15]. 這個(gè)是前一段話 哪位給解答一下 |
