Note: The effect of reaction temperature on the size of nanoparticles Reaction temperature is different in determining the size and the particle size distribution plays an eye-catching role. A suitable reaction temperature produces narrow nanocrystals.
At such temperatures, the nucleation and growth stages occur separately and can even delay the onset of the growth phase, so that after nucleation has taken place, in general, increasing the reaction temperature increases the rate of the reduction reaction. However, regarding the effects of pouring temperature and particle size of nanomaterials, the optimum temperature for the production of electrochemical nanoparticles by chemical reduction method was obtained experimentally for the production conditions. In the case of nanoparticle synthesis, the chemical reduction method, which increases the size of the electrochemical nanoparticles and increases the non-uniform particles by increasing the reaction temperature. This behavior occurs at lower temperatures, slower nucleus growth, smaller particle size, and greater particle uniformity. The effects of temperature on the chemical reduction of nanomaterials are investigated and the effect on electrochemical particles that temperature has significant effects on the shape, size and shape of nanoparticles. At low temperatures (zero degrees) the reaction rate is very low and the process of completing the reduction reaction takes hours. At temperatures between 10 and 55 degrees Celsius, as the temperature increases, the reaction rate increases and the particle size increases.
As the reaction temperature increases, the particle size decreases. The phenomenon of increasing the nucleation clock is proportional to the increase in temperature, which reduces the particle size. The revival of electro-chemical reaction, nano-sized particles produced at the temperature of 09 ° C than the particles produced at 59 degrees Celsius, the particles smaller. The effect of reaction time on the size of nanoparticles The reaction time is also one of the important parameters in controlling the size and size of the final product. Reaction Strategy In the early stages of growth, smaller electrochemical nanoparticles can be obtained. The strategy damages the overall efficiency of the reaction, because the monitoring of the material in this case is partially converted to electrochemical nanoparticles. When the precursor is added to the reaction solution, immediately nucleate It starts and small nanocrystals are formed, which causes a marked change in the color of the solution. Over time, the nuclei produced stick together to form larger particles.
For this reason, a choice between reaction efficiency and particle size is necessary to deliver the electrochemical reaction over the reaction time. Also, as the reaction time increases , the shape and size of the particles produced become more uniform.
