Polyoxometalate (POM) nanoclusters are widely used in energy storage and sensors due to their excellent redox properties chemical stabilities. Three isomorphic Keggin-type compounds with nanostructures {(Ag4L6)(SiMo12O40)} (Ag-SiMo), {(Cu4L6)(SiMo12O40)} (Cu-SiMo) {(Cu4L6)(GeMo12O40)} (Cu-GeMo) [L = 4-Oxazol-2-ylmethyl-4H-(1, 2, 4)triazole]) were successfully synthesized applied as materials for supercapacitors electrochemical Cr (VI) by adjusting the types of metals POMs. Compared parent POMs, Ag-SiMo exhibits higher specific capacitance (502 F g–1 at a current density 2 A g–1) better sensitivity (54 μA μM–1). The findings indicate that incorporating metal–organic components substantially improves sensing capabilities This enhancement is likely several factors: introduction extra redox-active sites, stabilization porous framework, ion electron mobility. study provides feasible approach improve performance.
