Fabrication of BN modified Ti/PbO2 electrodes with tunable hydrophobic characteristics and their electrocatalytic performance

Ultralong-lifetime Ti/RuO2–IrO2@Pt anodes with a strong metal–support interaction for efficient electrochemical mineralization of perfluorooctanoic acid

“…The electrode coatings had appropriate hydrophobicity that was more beneficial for reducing the oxygen evolution of the electrode material and enhancing the generation and reaction efficiency of ˙OH. 29,30 The TEM images (Fig. 1c) clearly show the spherical and highly crystalline Pt/Ru–Ir oxide particles after calcination, with an average particle size of about 4.0 ± 0.5 nm and a minor degree of particle aggregation, but these cannot be observed on the surface of the Ti/RuO 2 –IrO 2 –Pt electrode (Fig.…”

Electrodeposition and Catalytic Performance of Hydrophobic PbO2 Electrode Modified by Surfactant OP-10

“…At the same time, the hydrophobicity of the electrode surface will affect the electrocatalytic performance of the electrode, when the electrode surface is hydrophobic, the content of hydroxyl radicals adsorbed on the electrode surface would be reduced, and more free hydroxyl radicals would be formed, which improve the utilization rate of hydroxyl ions and help to improve the electrocatalytic performance of the electrode. 51 Fourier transform infrared spectroscopy (FTIR) analysis.-It can be seen from Fig. 6( ) that the wave number is 3411.08 cm −1 corresponding to the stretching vibration region of −OH, 1712.07 cm −1 is the absorption peak of aromatic ether, 1478.14 cm −1 and 727.40 cm −1 correspond to the absorption peaks of benzene ring and m-disubstituted benzene ring respectively, 1166.02 cm −1 and 1036.…”

CMS and Nd Co-Modified PbO2 Electrodes with Enhanced Lifetime and Electrochemical Activity for the Degradation of Bisphenol S

“…Samples were respectively taken at times of 0, 5, 10, 20, 30, 60, 90, and 120 min to measure COD and BPS concentration, and the degradation efficiency of the target pollutants was evaluated. Furthermore, the effects of different process parameters including initial BPS concentration (20-200 mg l −1 ), electrolyte concentration (Na 2 SO 4 , 0.02-0.50 M), current density applied (10-50 mA cm −2 ), and initial pH (3)(4)(5)(6)(7)(8)(9)(10)(11) were investigated.…”

“…PbO 2 has the advantages of low preparation cost, good electrical conductivity, and corrosion resistance, and is one of the most widely used electrode materials for wastewater treatment. [8][9][10] Traditional titanium-based lead dioxide electrodes have disadvantages such as low stability of the active layer and short service lifetime. The reason for the failure of the electrode is that the stress during the growth of the metal oxide on the titanium substrate is large, which causes the coating to fall off; the active oxygen generated during the electrochemical oxidation process reaches the substrate through the surface gap, and the titanium substrate is oxidized to form stable TiO 2 insulation layer, resulting in a sharp increase in resistance and causing the coating to peel off; and the electrolyte infiltrating the substrate through the gap, causing the coating to peel off.…”
