In real seepage water, the PEC method achieved a capacity of 0.67 gU m -3 •h -1 without further optimization, which is 17 times faster than the photocatalytic method using identical photocatalyst, at a compulsory energy cost of 125 kWh/kgU ($15.63/kgU). In summary, our work introduces a facile strategy to simultaneously address the depletion of conventional U resources and the negative environmental impacts of U mining industry, contributing to the sustainability of nuclear power industry.
