ABSTRACT

TiO2's capacity as a photocatalyst and its great performance in photovoltaic applications have been the subject of extensive research .In this study, TiO2 nanoparticles were examined for phenol degradation under UV radiation in a range of pH conditions.SEM and XRD were employed to describe the TiO2 nanoparticle. The outcomes demonstrated that Titanium dioxide nanoparticles have an anatase-like structure and a 26 nm particle size. Breakdown of phenol by UV light had phenol remove of 77% phenol was destroyed in 2 hours, whereas the degradation of phenol without UV rays had removal efficiency of 15% dye was destroyed in 2 hrs, according to the efficiency of photocatalysis of TiO2 nanoparticle. It said that UV light could trigger the efficiency of photocatalysis of Titanium dioxide nanoparticles. The breakdown of phenol 15% is no a photocatalysts activity; rather, it is the destruction of phenol by Titanium dioxide nanoparticles without the availability of UV light. Titanium dioxide nanoparticles' photocatalytic activity is pH-sensitive. Titanium dioxide nanoparticles have the efficiency of photocatalysis of 77% in neutral conditions (pH 7.0), the highest photocatalytic activity occurs.
