The key innovation of the work lies in enhanced visible light activity, lesser H<sub>2</sub>O<sub>2</sub> oxidant content, and faster removal with less sludge generation. Comprehensive characterizations revealed a lower bandgap and rapid charge separation, which reflected on the improvement of the performance of the photocatalyst. The bimetallic MOF achieved 99.01% removal of CV under the visible 100 W Xe light source with six times faster rate than the pristine MIL-53(Fe) and also 82.42% CV removal under irradiation of sunlight in 60 min at optimized conditions of 20.0 ppm dye concentration, 444 ppm H<sub>2</sub>O<sub>2</sub> concentration, and 1.0 g/L catalyst loading. The composite maintained good recyclability up to five consecutive cycles with a removal of 78.89% CV.

Remarkably enhanced in vitro antitumor activity was observed: S3 showed 4.3-fold higher cytotoxicity than satraplatin in HCT-116 cells, with superior efficacy against drug-resistant cells. S5 demonstrated 22-fold greater antiproliferative activity than both parental satraplatin and CBD alone in A549 cells, likely attributable to its haloacetic axial group enhancing mitochondrial targeting for trifunctional synergistic antitumor effects.
