Embodiment 1

[0030] Example 1MoO 3 Preparation of / P6ICA composite electrode material

[0031] Preparation of MoO by Electrodeposition 3 Base:

[0032] Cut the FTO conductive glass into a size of 0.7cm×5cm with a glass knife, clean it with ethanol, acetone, and ultrapure water for 10 minutes, and then use a multimeter to measure the FTO conductive surface; weigh 0.088g of ammonium molybdate tetrahydrate [(NH 4 )Mo 7 o 24 4H 2 O] dissolved in 5ml of water, ultrasonic 5min until completely dissolved, as the electrochemical polymerization solution 1.

[0033] A one-chamber three-electrode system was used for deposition. First, sand the Ag with a diameter of 0.5mm until it is smooth, burn the Pt wire with a diameter of 0.3mm to red with an open flame, then connect the Ag wire to the working electrode and the Pt wire to the reference electrode; 6mol L -1 In the hydrochloric acid solution, the electrolysis process occurs under the condition of a constant potential of 1.5V and 100s. When ...

Abstract

The invention belongs to the technical field of supercapacitors, and discloses a MoO3 / P6ICA composite electrode material and a preparation method thereof and a supercapacitor. The MoO3 / P6ICA compositeelectrode material is a MoO3 / P6ICA composite electrode material formed by taking molybdenum oxide (MoO3) as a substrate and electrically polymerizing poly6carboxyl indole (P6ICA). The MoO3 / P6ICA composite electrode material is good in stability and has good electrochemical, electrochromic, capacitive and electrochemical stability.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to MoO 3 / P6ICA composite electrode material and its preparation method and supercapacitor. Background technique [0002] At present, the problem of energy shortage in the world is becoming more and more serious, and the development of renewable energy and efficient green energy utilization is indispensable. Therefore, in recent years, how to conduct research on the rational and effective use of energy has become a hot spot. As an important energy storage technology, supercapacitors have been favored by more and more researchers because of their fast charge / discharge rate, high power density, large specific capacity and good cycle stability. At the same time, in the current research, the electrochromic smart window is also a way to effectively use energy. This kind of smart window can adjust the incident of external light through electrochromism, thereby reducing the coolin...
