With the fast exhaustion of fossil fuels, the need for new energy storage materials to meet the world's massive energy demand has inclined tremendously. Inorganic components with conducting polymer based...

Facile synthesis of platelet‐like zirconium tungstate nanostructures for high‐performance supercapacitors

“…35 Moreover, the appearance of a strong stretching band at 670 cm À1 was indicative of O-W-O stretching related to WO 4 tetrahedron. 19,35,36 Furthermore, FTIR spectra recorded for the series of ZrW 2 O 8 NPs prepared under similar optimized conditions was given in Figure S1. The peak position and structural vibration of each spectral line closely resemble with one another, which indicates the reliability of the synthetic procedure.…”

“…Hence, the electrodes should be made of various nanostructured materials, such as metal oxide nanoparticles, conductive polymer materials and carbon nanomaterials, in order to achieve high capacitive performance. 19 Interestingly, Transition Metal Oxides (TMOs) are found to be more supportive for the charge storage in order to attain high capacitance because of their sufficient energy density as well as chemical stability. 20 Most recently, many research works have been devoted to develop TMOs based materials for energy applications.…”

“…TMTs hold considerable promise for use in a variety of fields, including SCs, Liion batteries, solar water oxidation, and dielectric ceramics. 19 In contrast, there are still few reports on TMTs being used as electrode material for highperformance SCs. Therefore, in recent years, researchers have paid close attention in the development of metal tungstates for energy storage applications.…”

“…21,25 In addition, the multiple oxidation states in the mixed or simple binary MOs outpace the simple MO in terms of electrochemical applications. 24,26,27 Based on the above consideration, several studies are performed to utilize the advantages of tungstate-based metal oxides in the fields of batteries, supercapacitors etc., 19,28,29 Thus, we proposed to design ZrW 2 O 8 NPs as electrode material in supercapacitor. Although different applications were proposed on ZrW 2 O 8 NPs, the published research literature in the field of energy storage system is still limited.…”

“…However, developing appropriate electrode material for SCs has become an important component to increase the performance. Hence, the electrodes should be made of various nanostructured materials, such as metal oxide nanoparticles, conductive polymer materials and carbon nanomaterials, in order to achieve high capacitive performance 19 …”
