Abstract

Abstract To enhance the supercapacitive performance, SnO 2 was applied onto Ti 3 C 2 by microwave irradiation. The increased layer spacing identified by XRD indicates the intercalation of Sn 2+ . SEM and TEM showed nano-sized SnO 2 particles were anchored on the surface of Ti 3 C 2 . Electrochemical testing results revealed the capacitance of SnO 2 -Ti 3 C 2 was nearly two times as high as that of pristine Ti 3 C 2 (at 1 A g −1 ). After 8000 charge-discharge cycles (at 3 A g −1 ), 82% of the specific capacitance of SnO 2 -Ti 3 C 2 electrode was retained. The findings are a clear indication of a new technical route for the development of novel nanomaterials with enhanced performance.
