摘要

Transitional metal oxide nanomaterials are considered to be potential electrode materials for supercapacitors. Therefore, in the past few decades, huge efforts have been devoted towards the sustainable synthesis of metal oxide nanomaterials. Herein, we report a synergistic approach to synthesize spherical-shaped CoMoO _(4) electrode materials using an inorganic–organic template via the hydrothermal route. As per the synthesis strategy, the precursor solution was reacted with the organic compounds of E. cognata to tailor the surface chemistry and morphology of CoMoO _(4) by organic species. The modified CoMoO _(4) nanomaterials revealed a particle size of 23 nm by X-ray diffraction. Furthermore, the synthesized material was scrutinized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, field emission scanning electron microscopy and energy dispersive spectroscopy. The optical band gap energy of 3.6 eV was calculated by a Tauc plot. Gas chromatography-mass spectrometry identified cyclobutanol (C _(4) H _(8) O) and octodrine (C _(8) H _(19) N) as the major stabilizing agents of the CoMoO _(4) nanomaterial. Finally, it was revealed that the bioorganic framework-derived CoMoO _(4) electrode exhibited a capacitance of 294 F g ~(?1) by cyclic voltammetry with a maximum energy density of 7.3 W h kg ~(?1) and power density of 7227.525 W kg ~(?1) . Consequently, the nanofeatures and organic compounds of E. cognata were found to enhance the electrochemical behaviour of the CoMoO _(4) -fabricated electrode towards supercapacitor applications.

Cognata的有机化合物反应，以通过有机物种定制COMO_（4）的表面化学和形态。改性的COMO _（4）纳米材料通过X射线衍射揭示了23nm的粒径。此外，通过傅立叶变换红外光谱，X射线光电子能谱，场发射扫描电子显微镜和能量分散光谱仔细审查合成材料。 3.6eV的光带隙能量由Tauc图计算。气相色谱 - 质谱法鉴定环丁醇（C _（4）H _（8）O）和辛丁（C _（8）H _（19）N），为COMO _（4）纳米材料的主要稳定剂。最后，揭示了生物有机框架 - 衍生的COMO _（4）电极通过循环伏安法表现了294f g〜（α1）的电容，其最大能量密度为7.3 W H kg〜（α1）和功率密度7227.525 w kg〜（？1）。因此，发现E.Cognata的纳米粒细胞和有机化合物增强了COMO _（4）-Fabricated电极朝向超级电容器应用的电化学行为。
