Wolframite (FeWO4) is a type of polyoxometalate known for its high chemical stability and electronic properties, which makes it an excellent photocatalyst. While FeWO4 has been widely utilized in the domain organic catalysis, there are currently no documented reports regarding use degradation U(VI). In this study, effect changing microscopic morphology catalyst to enhance photocatalytic activity was explored. We effectively adjusted microstructure crystallinity by varying hydrothermal synthesis temperature, subsequently analyzed detail using synchrotron radiation theoretical calculations. Additionally, rate U(VI) nuclear wastewater reached 98.8% samples synthesized at 200 °C, coexisting ions on performance studied, results showed that certain amounts Na+, Mg2+, K+, Ca2+ almost negligible, still maintained more than 90% initial after six cycles, highlights wide application prospects field treatment future. Therefore, exhibits uranium-extraction ability, anti-interference stability, low-cost advantage. It holds great extracting radioactive uranium from wastewater.
