Synthesis and Photocatalytic Activity of Pt-Deposited TiO₂ Nanotubes (TNT) for Rhodamine B Degradation.

ABSTRACT: Dye wastewater has attracted more and more attention because of its high environmental risk. In this study, a novel TiO₂ nanotube (TNT) catalyst was prepared and its morphology and structure were characterized. The synthetic catalyst was used to degrade Rhodamine B (RhB) under UV light and evaluated for the application performance. According to the characterization results and degradation properties, the optimum synthetic conditions were selected as 400°C calcination temperature and 10 wt% Pt deposition. As a result, the degradation efficacies were sequenced as TNT-400-Pt > TNT-500-Pt > TNT-400 > TNT-300-Pt. In addition, the effect of pH and initial concentration of RhB were explored, and their values were both increased with the decreased degradation efficacy. While the moderat
