A Needle‐Like MOFzyme with High Aspect Ratio and Extended pH/Temperature Working Ranges for Total Antioxidant Capacity Determination and Oxidant‐/Light‐Free Dye Degradation

of 0.12 mM, a wide pH range of 3.0-8.0, and an extended thermal range of 25-70°C were obtained, revealing their practical applicability for developing pH- and temperature-independent protocols. The MOFzyme was then utilized for the determination of TAC using trolox as a model antioxidant, providing a linear range of 0.0-200.0 μM, and a very low detection limit of 1.0 μM was obtained for TAC quantification. The selectivity studies showed that other coexisting materials cannot interfere with sensor response. The intra-day and inter-day reproducibility assays showed a %RSD as low as 1.7% and 2.36% for the sensor. The dye degradation was performed using rhodamine B as a model molecule, revealing 99.7% degradation within 40.0 min without any oxidant/light irradiation and 10 cycles of reusability. The applicability of the MOFzyme for real food and sustainable environmental applications was proved.
