·OH radicals produced via an eco-friendly O₃ decomposition reaction in water are employed in a wide range of applications. In this work, three-dimensional (3D) β-PbO₂/Ta₂O₅ and Pt/Ta₃N₅ samples with a rod-like morphology were successfully fabricated and coupled to carry out electrochemical ozone production (EOP) and hydrogen evolution reaction (HER), respectively. Moreover, the results on the in-situ electrodegradation of dimethoate also indicate that the β-PbO₂/Ta₂O₅ NRs show a great potential to be used in advanced oxidation processes (AOPs) applications. Experimental results and theoretical calculations reveal that the excellent EOP performance of the β-PbO₂/Ta₂O₅ NRs can be attributed to the adsorption energy of the O species, which can be modulated via the synergic effect between β-PbO₂ and Ta₂O₅. This work provides a reference for the development of stable electrocatalysts with high efficiency for the simultaneous production of O₃ and H₂ in environmental applications and energy conversion.
