- The study explores how polishing 3D-printed titanium (Ti) electrode substrates before anodisation affects the formation of TiO nanotube arrays, which are used for photoelectrocatalytic treatment of hard-to-degrade pollutants like organophosphate flame retardants (OPFRs).
- Differences in surface morphology were observed, with polished electrodes showing more uniform nanotubes and handling water differently, but both polished and non-polished electrodes had similar electrochemical performance.
- The effectiveness of degrading OPFRs was significantly influenced by the purity of the water used, with purified water improving degradation rates compared to tap water, indicating that electrode preparation might not be essential for effective treatment.
