Description
Summary:This study aimed to fabricate a novel TiNT-RuO2 electrocatalyst to produce active chlorine with the capacity to oxidize recalcitrant organic matter. Titanium oxide nanotubes (TiNTs) were first grown via Ti foil anodization in potentiostatic mode in an ethylene glycol solution containing H2O and NH4F and then annealed at 450°C in air. RuO2 nanoparticles were deposited on the TiNTs using a hybrid strategy that included pulsed electrodeposition of the Ru nanoparticles, followed by thermal treatment. X-ray diffraction (XRD) only revealed peaks related to metallic Ti and anatase (TiO2) for the TiNTs, whereas additional peaks associated with the tetragonal RuO2 structure were shown for TiNT-RuO2. Scanning electron microscopy showed a well-organized structure for the TiNTs with an average inner diameter of approximately 185 nm for the NTs, while RuO2 nanoparticles (size
