文摘

TiO2 nanotubes were grown on a PbO2-based anode to produce a larger band gap that favors HO radical production, destroys ofloxacin and presents lower energy consumption. The ofloxacin electrodegradation pathway was analyzed. The mass transfer impact to electrochemical oxidation efficiency was analyzed using a differential column batch reactor.
