Description
The estimation of the particle size and particle size distribution is of importance in the catalysts study. In catalysts, atoms within NPs, in general, and those located at corners, edges and kinks, particularly, show a high catalytic activity due to their low coordination numbers and their great tendency to raise this number by coordinating with other species in the vicinity.
Plasma technology has taken attraction as a very useful tool for several modern researches and applications, such as plasma-mediated synthesis of nanomaterials, plasma-catalysis for environmental applications. In the present study we used glow discharge plasma to reduce the particle sizes of TiO2 catalysts. We started with the simplest possible structure as catalysts, where we will extend our studies to more complicated ones in the future.
Small angle x-ray scattering (SAXS) technique was employed to obtain scattering profile of the rutile TiO2 samples before and after plasma treatments for different treatment times and pressures.
