Visible light induced photocatalytic degradation of 2-nitrophenol at high concentration implementing rGOTiO2: mathematical modeling behavior.

This investigation implemented the nanomaterial rGOTiO2 for photodegradation of 2-nitrophenol solution at high concentrations. The 2-nitrophenol photodegradation was carried out in the presence of three kinds of light sources in the visible range spectrum. The results demonstrate that the nanomaterial rGOTiO2 is capable of pollutant degradation even in the low power light source (10 W), and have high activity under sunlight. The degradation of 2-nitrophenol was monitored by UV-vis spectroscopy, adjusting method by least squares for nonlinear functions. The equation represents the material photocatalytic activity under sunlight, which excludes climatic and variance factors. This equation predicts the pure rGOTiO2 behavior under sunlight; this will enable future research to develop more advanced processes.
