Abstract
In this paper, we present the experimental results of the photocatalytic properties evaluation of the niobium pentoxide semiconductor oxide and its performance in processes photoinduced of Rhodamine B and Atrazine degradation, under visible light irradiation. The sample photocatalysts were synthesized via pechini method. The nanoparticles structure of the samples was studied by X-ray diffraction, Brunauer–Emmett–Teller, Raman spectroscopy, UV–Vis and scanning and transmission electron microscopy. The increase in the calcination temperature during the synthesis resulted in enhanced crystallization, but decreased mesoporosity of the samples.
