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 Pbo 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 electrodes form and
component, the development of new electrode preparation methods, and research on the mechanism of
electrode failure for guiding the modification process
