Synthesis and Characterization of N and Fe-Doped TiO Nanoparticles for 2,4-Dimethylaniline Mineralization.

The present study aimed to evaluate the feasibility of developing low-cost N- and Fe-doped TiO photocatalysts for investigating the mineralization of 2,4-dimethylaniline (2,4-DMA). With a single anatase phase, the photocatalysts showed high thermal stability with mass losses of less than 2%. The predominant oxidative state is Ti, but there is presence of Ti associated with oxygen vacancies.

Degradation of the insecticide propoxur by electrochemical advanced oxidation processes using a boron-doped diamond/air-diffusion cell.

A solution with 0.38 mM of the pesticide propoxur (PX) at pH 3.0 has been comparatively treated by electrochemical oxidation with electrogenerated HO (EO-HO), electro-Fenton (EF), and photoelectro-Fenton (PEF).
