Study on size control of TiO2 nanoparticles synthesized using solution plasma process

Abstract

The research was conducted to study the size control of TiO2 nanoparticles synthesised. The TiO2 nanoparticles was formed using the solution plasma process. This method is an electrolysis of water-based experiment. When compared to other methods, the solution plasma method offers both a shorter synthesis time as well as a simple setup. Researches conducted on nanomaterials have proven that these materials tend to have varying properties when compared to bulk metals. With this, being able to vary the sizes of the TiO2 nanoparticles meant being able to study its possible future applications. One being using these nanoparticles for the fabrication of solar cells. Varying the sizes of these nanoparticles could bring a difference in the reactivity which can help enhance the performance of the solar cells. In order to vary the sizes of the nanoparticles, the concentration of the electrolyte was varied. During the research, it was found that the sizes of the TiO2 nanoparticles decreases with the increase in the concentration of the electrolyte.

Submerged Discharges in Liquids for Nanoobject Synthesis: Expectations and Capabilities

“…This behavior is attributed to the way the discharge erodes the electrodes, as discharges are weaker (the glow is said to be not "full") in NaOH beyond 0.5M. Yii et al [123] also observed with TiO2 nanoparticles that their mean size increases when the concentration of K2CO3 increases from 0.1 to 1M.…”
