Microwave-assisted synthesis of SnO2-Ti3C2 nanocomposite for enhanced supercapacitive performance

To enhance the supercapacitive performance, SnO2 was applied onto Ti3C2 by microwave irradiation. The increased layer spacing identified by XRD indicates the intercalation of Sn2+. SEM and TEM showed nanosized SnO2 particles were anchored on the surface of Ti3C2. Electrochemical testing results revealed the capacitance of SnO2-Ti3C2 was nearly two times as high as that of pristine Ti3C2 (at 1 A g(-1)). After 8000 charge-discharge cycles (at 3 A g(-1)), 82% of the specific capacitance of SnO2-Ti3C2 electrode was retained. The findings are a clear indication of a new technical route for the development of novel nanomaterials with enhanced performance. (C) 2017 Elsevier B.V. All rights reserved.
