Electrochemical oxidation of aniline at mono and bimetallic electrocatalysts supported on carbon nanotubes

Electrocatalytic degradation of aniline by Ti/Sb–SnO2, Ti/Sb–SnO2/Pb3O4 and Ti/Sb–SnO2/PbO2 anodes in different electrolytes

“…S3 of the supplementary materials). Therefore, combined with literatures [2,16,45] and experimental results, a simple possible degradation mechanism of aniline by ECT was proposed (Fig. 9).…”

“…Meanwhile, the toxicity of "steady process" was also occurred at the sample with darker color. Some researchers [2,16,45] found that due to the high concentration aniline, some intermediate polymers or oligomers with lower biotoxicity could be formed easily by electrochemical polymerization. In addition, the color of the intermediate polymers was dark brown.…”

“…Compared with the above methods, electrocatalytic oxidation is a more promising method due to its high efficiency, versatility, simplicity, flexibility and environmental friendliness [13][14][15][16]. Therefore, the electrocatalytic oxidation method has been widely used to treat aniline wastewater in recent years [16][17][18][19].…”

Direct fabrication of lamellar self-supporting Co3O4/N/C peroxymonosulfate activation catalysts for effective aniline degradation

“…Advanced oxidation processes based on Å OH or Å O 2 À have been commonly used in the degradation of persistent organic pollutants in water. For example, lots of technologies have been applied to generate Å OH or Å O 2 À radicals for aniline degradation including Fenton process [6,7], photocatalysis [8][9][10], catalytic wet oxidation [11][12][13], ozonation [14][15][16] and electrochemical oxidation [17][18][19][20]. However, these technologies have several limitations such as metal leaching, low pH rang (3)(4), excessive sludge production, and the high hydrogen peroxide transportation cost [1,4].…”

Synthesis of acidified palygorskite/BiOI with exceptional performances of adsorption and visible-light photoactivity for efficient treatment of aniline wastewater

“…However, aniline-containing wastewater, even in very low concentration, is harmful to human and aquatic life. As a well-known carcinogenic, aniline can also transform the hemoglobin into metahemoglobina causing anoxia, erythrocyte damage and affect the spleen (Ferreira et al, 2015). So increasing attention has been paid to efficient aniline removal technologies.…”
