| Abstract | ||||
| In our time there is an urgent need for treatment of effluents, so we can use plasma as a source of energy to generate high energy electrons and active species used in the treatment process. We herein use microwave plasma discharge to generate titanium dioxide nano particles as a catalyst material. The X-ray diffraction (XRD) analysis confirms the formation of polycrystalline anatase titanium dioxide, The High resolution Transmission Electron Microscopy (HRTEM) examine the particle size, and from this analysis it can be estimated that the particle size of the formed powder in nano scale ranging from ~18 ππππ to ~35 ππππ. The specific surface area and pore size of the mesoporous anatase ππππππ2 nano crystallites are calculated by using the nitrogen adsorption and desorption isotherms and it was found that the surface area of ππππππ2 nanoparticles is 226.458 ππ2/ππ, the total pore volume is equal to 0.1756 ππππ/ππ for pores smaller than 202.3 Å (radius) at ππ/ππππ = 0.95014 and the average pore radius 15.5103Å. The optical activity of the titanium dioxide powder is proved by testing its great ability in degradation of methylene blue, MB. | ||||
