Fabrication of sulfur-doped TiO2 nanotube array as a conductive interlayer of PbO2 anode for efficient electrochemical oxidation of organic pollutants

Efficient and stable anode materials are in high demand for the electrochemical oxidation of toxic and persistent organic pollutants in wastewater treatment. Herein, a highly structured and conductive sulfur-doped TiO2 nanotubes was fabricated as an interlayer for the Ti-based PbO2 anode (S-TiO2 NTA-PbO2). The novel S-TiO2 NTA-PbO2 anode exhibited a better electrochemical oxidation capability and hydroxyl radical production activity for organic...
