AI Technical Summary

Technical Problem

When the existing vertically oriented blue-black TiO2 nanotube array (TNA) is used as an anode material, the charge transfer is limited, resulting in unsatisfactory electro-oxidation ability, making it difficult to effectively degrade persistent organic pollutants, especially tetracycline antibiotics.

Method used

Nanoparticles were uniformly filled in the TNA channel to form a CoMo-BTNT anode. A Co-Mo oxide layer was deposited by direct current electrodeposition and annealed to improve the conductivity and electrocatalytic performance. Peroxymonosulfate (PMS) was combined with active oxygen species such as sulfate radicals (SO4·-) to construct an electrically assisted activation PMS degradation system.

Benefits of technology

The conductivity and oxidation capacity of the anode were significantly improved, and tetracycline in water could be degraded quickly and efficiently with selectivity in a wide pH range, with a degradation efficiency of up to 91.63%.
