Electrochemical oxidation of dyes on oxide lead anode with the involvement of active oxygen species

Photoelectrocatalytic activity of silicon nanowires decorated with electroless copper nanoparticles and graphene oxide using a plasma jet for removal of methyl orange under visible light

“…However, these techniques are commonly expensive in their implementation and have a high environmental impact; for these reasons, oxidative processes, such as ozonation or chemical and photo-oxidation by the Fenton process, have been proposed for removing dyes. 4,5 Furthermore, among oxidative techniques, the electrochemical processes are attractive due to their facile control by current density and potential, 6 besides offering the possibility of combining with light irradiation to produce photoelectrochemical processes.…”

Composite Electrodes PbO2-Nafion®

“…[1][2][3] They can be fabricated by electrodeposition from aqueous solutions, have high electrical conductivity, low cost, satisfactory corrosion resistance and high electrocatalytic activity in reactions proceeding at high anode potentials with oxygen-containing radicals participation. [4][5][6] At the same time, materials based on lead dioxide have still not found wide practical application, which is caused by unsatisfactory mechanical properties namely, inadequate adhesion of the active layer to the substrate. 7 The rate of mechanical destruction of the oxide layer of dimensionally stable anode is proportional to the intensity of oxygen evolution.…”
