Abstract

Emerging pollutants are not included in monitoring programs by environmental and health agencies, and therefore, do not have environmental control regulations. These pollutants originated by anthropogenic actions are volatile organic and pharmaceutical compounds, which are found in air and urine/water, respectively. In addition, if they are not treated before reaching the environment they can be responsible for well-being population loss. Thus, an important field of study is the search for alternatives to recover contaminated air and urine with emerging pollutants. Electrochemical Oxidation Processes (EOP) are methods with high efficiency in organic degradation due to their high oxidative species productions and can be applied both for air and urine decontamination. Consequently, we propose a novel boron-doped ultra nanocrystalline diamond/dioxide titanium nanotube/titanium growth without seeding (B-UNCDWS/DTNT/Ti) as a porous composite to be used as electrode material to treat air and urine contaminated with emergent pollutants using EOP. This composite is very attractive for electrochemical applications by its large surface area provided by the homogeneity and porosity by combining the B-UNCDWS as well as DTNT singular properties.
