This review article discusses the potential of using metal-doped TiO2 as a photocatalyst for dye degradation in water. TiO2 is a promising photocatalyst but is limited due to its fast electron-hole recombination rate and vast bandgap energy. Metal dopants have enhanced the photocatalytic activity of TiO2, especially noble metal doping, due to the synergistic effects between the metal dopants and TiO2. The review summarizes experimental studies on photocatalytic dye degradation using metal-doped TiO2 and compares the degradation performance between doped and undoped TiO2. The authors emphasize the importance of understanding the interaction between metal dopants and TiO2 to improve the dye degradation activity and stability of metal-doped TiO2. The article highlights the optimum dopant concentration and preparation methods that can improve the textural or surface properties of doped TiO2 and enhance dye degradation capacity.
