Facile synthesis of NFL-ZnWO4 for pseudocapacitor applications

Abstract

In this report, NFL-ZnWO4 was synthesized by a hydrothermal route and investigated for application in supercapacitors for the first time. The physical and chemical characterizations of the prepared nanomaterial were analyzed by SEM, EDS, XRD and XPS, respectively. Supercapacitors study of CV, GCD and EIS revealed that NFL-ZnWO4 exhibits good electrochemical properties. The high specific capacitance value of 107.7 F g-1 was achieved at 5 mV s−1. These findings demonstrated that ZnWO4 could be a promising electrode material candidate and highly desirable for application of high property supercapacitors in the future.
