Advantages

6-fold larger active area

The 3D porous architecture provides many more electrochemically active sites, boosting degradation efficiency.

35-fold longer lifetime

The robust attachment of ATO coating on the foam substrate resists electrochemical corrosion, greatly extending the anode's service life.

Faster decolorization

Achieves 98.52% decolorization of Rhodamine B within 120 min, outperforming the plate anode.

Lower energy use

Specific energy consumption is only 3.34 kWh/m³/order per order of pollutant removal, reducing operating cost.

Applications

• Electrocatalytic wastewater treatment：Efficiently degrades dye wastewater with low energy consumption, suitable for practical engineering.
• Advanced oxidation processes：The anode generates strongly oxidizing species for deep mineralization of pollutants.
• Refractory organic wastewater：Maintains effective degradation even in high-concentration dye wastewater.
• Porous electrode manufacturing：Solvothermal deposition of ATO on Ti foam offers a scalable and simple fabrication route.
