Ag@Zn-MOF composites for high-capacitance energy storage and ultra-sensitive detection of Al³ ⁺ upto 0.156 ppm

The schematic illustrates the stepwise synthesis of a metal–organic framework (MOF) composite. Metal ions and organic linkers assemble into the MOF, followed by incorporation of an Ag precursor in a solvent under heating and cooling to form the final Ag-MOF composite. The resulting material is employed for sensing applications and enhanced battery performance. Arrows highlight the synthesis pathway, while icons and graphs represent the composite's sensing capability and electrochemical performance.
