Fabrication of Iron-Doped Fe@Zn-MOF Composite: Empowering Enhanced Colorimetric Recognition and Energy Storage Performance

Fe@Zn-MOF-2, an iron-doped Zn-MOF, was developed for sensing Gd 3+ and acetophenone and as an electrode material for energy storage. It exhibited a higher specific capacitance than Zn-MOF and retained 94.57% of its capacitance after 2000 cycles.
