摘要：
A colorimetric sensing method for salicylic acid (SA) was developed by designing and fabricating bimetallic oxide nanozymes. Firstly, by calcinating MIL-100(Fe)@PMo12 (MOFs@POMs) at different temperature, Fe-2(MoO4)(3)-Ts (T = 400celcius, 500 degrees celcius, 600 degrees celcius, 700 degrees celcius) nanoparticles (NPs) were successfully prepared. Secondly, by evaluating the peroxidase-like activities, Fe-2(MoO4)(3)-600 NPs shows the best peroxidase-like activity attributed to the Fenton-like effect and the synergistic coupling interaction between Mo and Fe. Finally, based on the specific complexation between SA and Fe3+, a sensitive colorimetric sensor for SA was established, which exhibits superior selectivity and interference with a detection limit of 0.11 mu M and a linear range of 10 to 100 mu M, the lowest LOD for SA to date, to the best of our knowledge.
