[0048] The preparation of described SWCNH-COOH is:

[0049] Disperse SWCNH into nitric acid solution, heat and reflux at 100-120°C for 12-24 hours, centrifuge the reaction solution after the reaction is completed, wash and filter repeatedly with deionized water until the filtrate becomes neutral, then vacuum at 80-90°C Dry to obtain SWCNH-COOH, and then disperse SWCNH-COOH in ethylene glycol to form a 0.5-1.0 mg / mL SWCNH-COOH dispersion.

[0050] The SWCNH-COOH and Fe 3 o 4 The nanocomposite of is:

[0051] A. Add 1.35g of FeCl to 100mL of SWCNH-COOH / EG dispersion 3 ·6H 2 O and 0.5g of cetyltrimethylammonium bromide, magnetically stirred at 50-60°C for 2-5h;

[0052] B. After the mixture is evenly dispersed, transfer the obtained mixed solution to the reaction kettle, and then place it at 180°C for constant temperature reaction for 12-18 hours;

[0053] C. After the reaction is completed, cool to room temperature, open the reaction kettle, centrifuge the composite, wash ...

Abstract

The invention discloses a ferroferric oxide / single-walled carbon nanometer angle composite electrode material and a preparation method thereof, wherein Fe3O4 nanometer particles are uniformly loaded on the surface of the carboxylated single-walled carbon nanometer angle, and the particle size of the Fe3O4 nanometer particles is 5-10nm. The specific capacitance of Fe3O4 at SWCNH is 245 - 305.5 F / g,which has the properties of electric double layer capacitance and Faraday pseudocapacitance. The synergistic effect of Fe3O4 nanoparticles and SWCNH greatly improves the capacitance performance, making it an ideal material for supercapacitors. The preparation method provided by the invention has the advantages of low cost, easy operation and control, low requirement on equipment, and convenient production and popularization in industrialization.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor electrode composite materials, and relates to an effective composite of transition metal oxides and carbon nanomaterials, in particular to a ferric oxide / single-wall carbon nanohorn composite electrode material and a preparation method thereof. Background technique [0002] With the development of society and economy, global fossil energy is increasingly consumed, environmental pollution is becoming more and more serious, and climate change is gradually affecting human life. There is an urgent need for human beings to study clean and sustainable renewable energy. Therefore, large-scale development of wind energy and solar energy, as well as automobile machinery driven by wind energy and solar energy. However, wind energy and solar energy are uncertain, intermittent and other characteristics are difficult to directly connect to the grid for power supply. Therefore, it is particularly import...
