Abstract

An improved solvothermal-synthesized 2D Fe-MOF (S-BUC-21(Fe)) achieves rapid photocatalytic reduction of Cr(VI) to Cr(III) within 6 min using tartaric acid under UV light and sunlight. The material enables continuous-flow wastewater treatment (100% efficiency for 10 h) and demonstrates ecological safety via Chlorella growth assays.
