MIL-101(Cr)@SnO2 was successfully synthesized via a impregnation-oxidation process and investigated as an electrochemical pseudo-capacitor material in 1M KOH electrolyte.Structural characterizations illustrate that SnO2 nanoparticles(NPs)disperse uniformly in the framework of MIL-101(Cr).The porous structure combined with SnO2 NPs brought a maximum specific capacitance of MIL-101(Cr)@SnO2 up to 100 F.g-1 at a scan rate of 5mV.s-1,which is far higher than MIL-101(Cr).Meanwhile,MIL-101(Cr)@SnO2 exhibits a good cycling stability over 500 cycles.
