Electrocatalytic oxidation is an effective water treatment method for degradation of organic pollutants, and the key to the technical advantages lies in anode materials with excellent performance. Ti-based anode can be conveniently prepared by coating a titanium substrate with a non-noble metal oxide such as lead, tin or manganese. At the same time, the anode materials with outstanding stability and catalytic activity can be obtained by various preparation and modification methods, which make it have great development prospects. Research progress on the stability optimization of non-precious metal oxide coating anode was reviewed from the perspective of substrate processing, intermediate layer optimization and surface modification. Catalytic activity enhancement was summarized from the aspect of surface synergism and the expansion of the action area, and the modification mechanism of coating anodes was commented. Finally, in order to promote the development of the electrocatalytic oxidation anode materials and its application in water treatment, development direction of non-precious metal oxide coated anodes was pointed out.
