Abstract
Efficient upcycling of uranyl from uranyl–containing radioactive organic wastewater is of utmost importance for the sustainable development of nuclear energy. In this work, an indirect electrochemical method to upcycle uranyl from radioactive organic wastewater is proposed. A cost-efficient self-standing polyarylether-based covalent organic framework electrode (PAE-COF-AO@CC) not only acts as an oxygen reduction reaction (ORR) catalyst for hydrogen peroxide (H2O2) production, but also provides chelating sites for uranyl ions and nucleation center for the following growth of studtite originating from the reaction between H2O2 and chelated uranyl. It’s clarified that the up-take studtite on PAE-COF-AO@CC…
