Advanced oxidative processes (AOPs) have been explored extensively for their application in waste water treatment and remediation. Their use of reactive oxygen species (ROS) to degrade organic pollutants that make their way into waterways shows promise for the complete removal of toxic materials. The implementation of electrocatalysts and photocatalysts as platforms the production of ROS allows for a green approach to AOPs, as it requires less additives for wastewater treatment and water purification. The use of catalysts for this process can often be economically unviable, as they commonly employ expensive noble-metals. To remedy this, the morphological and electrochemical character of more abundant materials, including metal-oxides such as TiO2, have been modified to increase their photocatalytic and electrocatalytic properties. In this presentation, we report on the development of nanostructured TiO2 catalysts for the photoelectrochemical degradation of atrazine, a common herbicide used in North America.Nanoporous TiO2 was directly grown on a titanium substrate using an anodization process. Characterization of the TiO2 electrodes was carried out by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. Electrochemical treatment of the nanoporous TiO2 was performed to further increase its catalytic activity towards the photoelectrochemical degradation of atrazine. The degradation process was monitored by UV-Vis spectroscopy, total organic carbon analysis and liquid chromatography-mass spectrometry. The effectiveness in the removal of Atrazine and the degradation mechanism will be discussed.
