<p>Oxidants such as peroxocompounds are commonly used in various applications, including wastewater treatment, soil remediation, and synthesis of high-added value products. In recent years, the electrochemical synthesis of oxidants has emerged as a sustainable approach, driven by the development of new anodes, such as boron-doped diamond films. Typically, electrochemically produced oxidants generated at boron-doped diamond anodes are used in situ, with both generation and application occurring simultaneously. This perspective explores the possibility of electroproducing oxidants for subsequent ex-cell applications. For such applications, the stability of the oxidant is a critical factor to consider. Electroproduced oxidants, such as peroxodisulfate, chlorine dioxide, or ferrate anions, have been successfully used ex-cell for the efficient removal of emerging contaminants from water. Additionally, studies highlight the effectiveness of ex situ applications of these oxidants in soil remediation, showing good performance both through direct soil treatment and the treatment of leachate from soil washing. Finally, electrochemically produced peroxodicarbonate and periodate have been used in the synthesis of high-added value organic compounds, with demonstrated applications in reactions, such as N- and S-oxidation, epoxidations, and vanillin synthesis.</p> Graphical Abstract <p></p>
