Sodium gadolinium molybdate (NaGd(MoO4)2) nanocrystals as electrode material for electrochemical supercapacitors |
| 초록 |
In this work, the well-crystallized sodium gadolinium molybdate (NaGd(MoO4)2) nanocrystals are synthesized by hydrothermal process using the oleic acid mediation and then utilized as electrode material for electrochemical supercapacitors. In this synthesis, oleic acid played an important role in the morphologically controlled synthesis of NaGd(MoO4)2 nanocrystals with various morphologies. The synthesized NaGd(MoO4)2 nanocrystals are thoroughly analyzed in terms of crystalline nature, structural, composition and quality by different morphological, structural and optical characterization tools. The electrochemical properties of synthesized NaGd(MoO4)2 nanocrystals based supercapacitors are examined by cyclic voltammetry (CV), galvanostatic charge-discharge(GCD) and electrochemical impedance spectroscopy (EIS). The fabricated supercapacitors posed moderately good specific capacitance of 167.5 F/g with excellent retention ability by maintaining over 80% capacity. Based on the properties of synthesized NaGd(MoO4)2 nanocrystals, it is expected that it can be a promising candidate as an electrode material for electrochemical supercapacitor application. |
