AI Technical Summary
Existing 2.5D electrocatalytic oxidation electrodes rely on strong magnetic bonding, have insufficient material flexibility, high interfacial resistance, and are difficult to load and unload flexibly through temperature changes. Furthermore, the traditional electrode composition/structure adjustment is limited and cannot adapt to complex and variable wastewater composition.
By loading antimony-doped tin dioxide onto molecular sieve particles and coating them with a polyurethane thermal expansion layer to form a secondary electrode, and bonding ruthenium-titanium mixed oxide onto a porous titanium matrix and spraying a polymer layer to form a primary electrode, the bonding state of the secondary electrode is controlled by temperature, thereby achieving stable bonding and dynamic adaptive adjustment between the primary electrode and the particle secondary electrode.
It achieves dynamic adaptive adjustment of electrode composition and structure, improves catalytic ability and stability, is suitable for complex wastewater treatment, and has higher organic matter degradation and conversion efficiency and in-situ material recovery characteristics.
