Emerging organic pollutants and refractory pollutants in water body have caused severe harm to the ecological environment and human health. Electrochemical advanced oxidation processes (EAOPs) are currently one of the most effective oxidation methods to deal with refractory organic pollutants. Electrode materials serve as the most critical component in influencing the EAOP performance. Dimensionally stable anodes (DSAs) have the advantages of dimensional stability, structural diversity, chemical stability, low oxygen evolution potential and long service life, etc. In this review, we comprehensively introduce several types of Ti-based metal oxide dimensionally stable anodes (Ti/MO_x DSAs) commonly used in EAOPs in the past five years, including Ti/IrO₂, Ti/RuO₂, Ti/PbO₂, Ti/Sb-SnO₂ and Ti/TiO₂. We summarize the modification methods including metal doping, composition adjustment, nanostructure construction, introduction of intermediate layers, compositing with carbon materials and formation of three-dimensional structures as well as the applications of these modified Ti-based DSAs in EAOP for the rapid degradation of various organic pollutants, and point out their advantages and current shortcomings of electrodes. Finally, we critically conclude the Ti-based DSA's current limitations and future development prospects.
