Abstract: Seeking for highly stable and effectively catalytic anode materials is the key of electrochemical water treatment. Although the titanium-based PbO2 electrode has excellent performance in the stability and catalytic efficiency，there is still rooms for improvement，thus the modification of titanium-based PbO2 electrodes becomes the central issue in the electrode material research. This review is aimed to present the research on character of PbO2，the structure of titanium-based PbO2 electrode and the modification for different layers in the electrode. This review is focused on the improvement and optimization of electrode preparation by using the modified titanium material as the electrode base，introducing the interlayer between the PbO2 layer and the titanium base，doping the PbO2 layer with the impurity elements and particles. The development of titanium-based PbO2 electrodes is given at the end of this review，which is the diversification of electrode’s form and component，the development of new electrode preparation methods，and research on the mechanism of electrode failure for guiding the modification process.
