SnO2\ quantum dots@ZIF-8 is successfully synthesized via a simple in-situ epoxide precipitation route and investigated as an electrochemical pseudo-capacitor material in 6 M KOH electrolyte. Structural characterizations illustrate the dispersion of SnO2 quantum dots in the ZIF-8. The porous structure combined with SnO2 quantum dots maximizes the utilization of active material, resulting in a high specific capacitance. A maximum specific capacitance of the SnO2 quantum dots@ZIF-8 can reach up to 931 F g(-1) at a scan rate of 5 mV s(-1), which is far higher than SnO2 quantum dots (241 F g(-1)) and ZIF-8 (99 F g(-1)). Meanwhile, SnO2 quantum dots@ZIF-8 exhibits a good cycling stability over 500 cycles. (C) 2014 Elsevier B.V. All rights reserved.
