Note: The effect of reaction temperature on the size of graphene nanoparticles and unlimited flowability in CNT and CNTs carbon nanotubes. The reaction temperature is different in determining the size and particle size distribution plays an ocular role. A good reaction temperature produces thin nanocrystals.
At such a temperature, the stages of nucleation and growth occur separately and can even be delayed at the beginning of the growth stage, so that after the nuclei are formed, in general, increasing the reaction temperature increases the rate of the regenerative reaction. However, in the case of temperature effects, the shear load and nanoparticle size of the material and the optimal temperature for the production of electrochemical nanoparticles by chemical regeneration method were obtained experimentally for the difficult conditions of production. In the case of synthetic nanoparticles, the chemical reduction method, which increases the reaction temperature, increases the size of the electrochemical nanoparticles and the non-uniform particles. This behavior is lower at lower temperatures, slower nucleus growth rates, smaller particle size, and greater uniformity of the required particles. The effects of temperature are studied by the chemical reduction of nanomaterials 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 regeneration reaction takes hours. At temperatures between 10 and 55 degrees Celsius, with increasing temperature, the rate of reaction increases and the size of the particles produced 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 size of the particles produced. 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 nanoparticle size of the reaction time is also one of the important parameters in controlling the size and size of the final product. The reaction strategy in the early stages of growth is to obtain smaller electrochemical nanoparticles. The strategy damages the overall efficiency of the reaction, because the monitoring of the material in this case is partially chewed into electrochemical nanoparticles. When the precursor is added to the reaction solution, it immediately forms a nucleus It starts and small nanocrystals are formed, which causes a clear change in the color of the solution. Over time, the nuclei produced stick together to form larger particles.
Conclusion :
At any time, more time is spent reacting, more ions to form nano-electro-chemical restoration, while larger particles are also the place to the next, in the form of particles Rehabilitation and since then only the particle size becomes larger. For this reason, it is necessary to choose between the efficiency of the reaction and the particle size to deliver the electrochemical reaction to the reaction time. Also, with increasing reaction time , the casting and size of the particles produced become more uniform.
