Summary: Electrocatalytic oxidation (ECO) is a highly efficient and environmentally friendly method for water treatment. This study focuses on the preparation of high-performance anodes with long service lifetimes. Porous Ti/RuO2-IrO2@Pt, Ti/RuO2-TiO2@Pt, and Ti/Y2O3-RuO2-TiO2@Pt anodes were fabricated using modified micro-emulsion and vacuum impregnation methods. These anodes exhibited large electrochemically active areas and long service lives. The Ti/Y2O3-RuO2-TiO2@Pt anode showed the highest degradation efficiency for tetracycline and consumed the lowest energy.

Summary: To reduce the global hazards of arsenic, arsenic-containing water needs to be purified. This study synthesized dimensionally stable TNTAs/SnO2/RuO2 anodes for efficient electrocatalytic oxidation of As(III) by successively electrodepositing SnO2 and RuO2 nanoparticles on TiO2 nanotube arrays. The optimized TNTAs/SnO2/RuO2-10 anode exhibited excellent electrochemical stability and longer service lifetime, with an oxidation conversion efficiency of As(III) still maintained at 98% even after 11 cycles of usage.
