Effect of Process Parameters on the Microstructure and Performance of TiO₂-Loaded Activated Carbon.

ABSTRACT: In this study, the visible-light-driven photocatalytic regeneration performance of TiO₂-loaded activated carbon (TiO₂/AC) was effectively improved. By carefully controlling the activation condition at 700 °C for 2 h with a 60% H₃PO₄ concentration and 3:1 TBT (tetrabutyl titanate) impregnation ratio, 90.5% of methylene blue (50 mg/L) was removed within 2 h by a low-dose TiO₂/AC (0.5 g/L), which was much higher than those obtained in previous studies on TiO₂/AC. Moreover, the effects of process variables on the microstructure and performance of TiO₂/AC were systematically investigated. The results showed that (1) the long period of activation time effectively inhibited the photogenerated charge carrier recombination
