Heterogeneous catalytic ozonation of dibutyl phthalate in aqueous solution in the presence of iron-loaded activated carbon

Fe3O4/multi-walled carbon nanotubes as an efficient catalyst for catalytic ozonation of p-hydroxybenzoic acid

“…The degree of mineralization also increased from 34.1 to 48.8 % in 30 min. These results were consistent with the previous studies (Yang et al 2014;Huang et al 2015). Higher dosage of Fe 3 O 4 /MWCNTs Fig.…”

Degradation of benzotriazole by a novel Fenton-like reaction with mesoporous Cu/MnO 2 : Combination of adsorption and catalysis oxidation

“…AOPs include ozonation [10], photocatalysis [11], and the Fenton process [12]. The classic Fenton oxidation showed some features [13], as nonselectivity oxidation derived by hydroxyl radical (·OH) generated from H 2 O 2 with Fe(II) [14], fast reaction rate, low cost, and low toxicity of reagents used.…”

Organic pollutants removal in wastewater by heterogeneous photocatalytic ozonation

“…Photocatalysis has shown to be adequate for the destruction of a wide variety of compounds, but the mineralization is slowly attained due to its low oxidation rate and the process is advantageous only for very dilute solutions (Hoffmann et al, 1995;Augugliaro et al, 2006). Ozone is a robust oxidizing agent (E 0 = 2.08 eV) compared with other agents, such as H 2 O 2 (E 0 = 1.78 eV), and can react with several classes of organic compounds through direct or indirect reactions (Oyama, 2000;Zhao et al, 2008Zhao et al, , 2009Cao et al, 2014;Xing et al, 2014a;Huang et al, 2015). Ozonation is more powerful than photocatalysis in organics degradation and more ascendant in treating highly concentrated samples (Agustina et al, 2005;Augugliaro et al, 2006).…”
