Atrazine, an herbicide used to control grassy and broadleaf weed, has become an essential part of agricultural crop protection tools. It is widely sprayed on corn, sorghum and sugar cane, with the attendant problems of its residues in agri-food and washing water. If ingested into humans, this residual atrazine can cause reproductive harm, developmental toxicity and carcinogenicity. It is therefore important to find clean and economical degradation processes for atrazine. In recent years, many physical, chemical and biological methods have been proposed to remove atrazine from the aquatic environment. This review introduces the research works of atrazine degradation in aqueous solutions by method classification. These methods are then compared by their advantages, disadvantages, and different degradation pathways of atrazine. Moreover, the existing toxicological experimental data for atrazine and its metabolites are summarized. Finally, the review concludes with directions for future research and major challenges to be addressed.

“…Photoelectrocatalytic systems were also proposed for the degradation of agrochemicals. For example, Xie et al examined the mechanism of photoelectrochemical removal of ATZ, using typical TiO 2 nanotube arrays obtained by anodization on Ti plates as working photoanode and a wide spectrum Xe lamp [100]. The best removal efficiency reached 96.8% at applied potential of 0.2 V vs. SCE in 2 h, with reaction rate constant of 1.72 h −1 .…”

Endocrine Disrupting Compounds (EDCs) comprise a class of natural or synthetic molecules and groups of substances which are considered as emerging contaminants due to their toxicity and danger for the ecosystems, including human health. Nowadays, the presence of EDCs in water and wastewater has become a global problem, which is challenging the scientific community to address the development and application of effective strategies for their removal from the environment. Particularly, catalytic and photocatalytic degradation processes employing nanostructured materials based on metal oxides, mainly acting through the generation of reactive oxygen species, are widely explored to eradicate EDCs from water. In this review, we report the recent advances described by the major publications in recent years and focused on the degradation processes of several classes of EDCs, such as plastic components and additives, agricultural chemicals, pharmaceuticals, and personal care products, which were realized by using novel metal oxide-based nanomaterials. A variety of doped, hybrid, composite and heterostructured semiconductors were reported, whose performances are influenced by their chemical, structural as well as morphological features. Along with photocatalysis, alternative heterogeneous advanced oxidation processes are in development, and their combination may be a promising way toward industrial scale application.

“…Furthermore, its valence band edge has appropriate energy values for the decomposition of water, thus generating hydroxyl radicals and other highly oxidizing species, intermediates in the oxygen evolution reaction . The TiO 2 photoanode has been used for degradation of several contaminants of emerging concern, phenol (a common compound in effluents of several industries), pharmaceuticals, , atrazine, and also for water disinfection …”

Solar-Driven Photoreactor for Water Remediation Based on n-Type TiO₂ and p-Type Ag/AgBiW₂O₈/Bi₂WO₆ Light-Responsive Air-Fed Gas Diffusion Electrodes

Photocathodes with multiphasic Ag/AgBiW2O8/Bi2WO6 (Ag/ABW/BW) particles, obtained by hydrothermal synthesis, were evaluated for light-assisted oxygen reduction reaction (ORR). Under irradiation, electrodes of Ag/ABW/BW deposited on FTO exhibited ORR cathodic photocurrent enhancement and impedance decreasing (p-type semiconducting behavior). The Ag/ABW/BW particles were deposited on graphite sintered with PTFE; under irradiation and flow of compressed air, this gas diffusion electrode (GDE) produced H2O2 from ORR. The air-fed GDE|Ag/ABW/BW photocathode was associated with an FTO|TiO2 photoanode and externally connected with a silicon solar cell. Irradiated by a solar simulator, this photoreactor was used for remediation of amoxicillin (AMX) aqueous solution. After 3 h, 53% of AMX was degraded, while with a bare GDE, the AMX removal was 30%. Smaller values (<15%) were obtained using Pt or a GDE|Ag/ABW/BW under N2 flow as the cathode, since these configurations preclude the H2O2 production from ORR. Thus, association of photoactive electrodes in this innovative solar-driven photoreactor provides a sustainable system for water remediation.
