Well, crystalline ZnO nanoparticles with size in the range of 30-70 nm are uniformly deposited on the graphene sheets, as evidenced by different techniques. The electrochemical properties of the prepared nanocomposites were examined by measuring the specific capacitance in 6 M KOH solution using cyclic voltammetry and galvanostatic charge-edischarge techniques. G-ZnO nanocomposites showed a good capacitive behavior with a specific capacitance of 122.4 F/g as compared to graphene oxide (2.13 F/g) and rGO (102.5 F/g) at 5 mV/s scan rate. Results demonstrated that such hybrid materials are promising electrode materials for high-performance supercapacitor applications. 2017-08-24T04:18:08Z 2017-08-24T04:18:08Z 2016 Article 2468-2284 http://repository.vnu.edu.vn/handle/VNU_123/58216 en application/pdf ĐHQGHN
