Anatase TiO2 crystal is considered to be an excellent and promising photonic material for applications in solar energy conversion systems because of its long photostability , low chemical corrosion, diverse shape, and cost effectiveness. However, the band gap of TiO2 is 3.2 eV that canlimit its effective applications. Therefore, the expansion of the effective light range for TiO2 is highly desired. In this study, Er3+-Yb3+-Ce3+ tridoped TiO2 nanopowder was synthesized using a facile one-step hydrothermal synthesis to extend effective light range to NIR via upconversion process of Yb3+-Er3+ pair ions and the activity of Ce3+ ions. The synthesized Er3+-Yb3+-Ce3+ tridoped TiO2 nanoparticles exhibited an excellent photocatalytic activity against an organic dye; Rhodamine B, and 4-chlorophenol. The photodegradation mechanism was proposed as well. Keywords: 4-chlorophenol, Upconversion, photodegradation, dope
