This paper describes an innovative system to produce nanoparticles based on thetheory of gas condensation in producing nanoparticles. In a vaccuum environment, the systemused the energy produced by high frequency induction to vaporize a pure zinc rod inside thecrucible. During the vaporization the chamber was filled with He gas, so the high-temperaturedvaporized metal can undergo momentum exchange with He gas and at the same time, induce thevaporized metal to move to the cold trap. Upon reaching the wall of the cold condenser, thevaporized metal instantly condensed, forming nanoparticles. The TEM image shows that theiraverage diameter was 30 nm, and the size was very consistent. In addition, the Zeta potential andaverage diameter of the ZnO nanofluid was also measured under different pH conditions todetermine the stability of the ZnO nanofluid. Moreover, in order to verify the practicability of thefabricated ZnO nanoparticles, the ZnO nanofluid was inspected by UV/Vis absorption spectrum,and the results show that ZnO nanoparticles absorption ability was within a wavelength range from350nm to 550nm
