[0021] The invention provides an all-solid WO 3 The preparation method of / tungsten mesh electrode material is characterized in that, comprises the following steps:
[0022] (1) Mix tungsten mesh, hydrogen peroxide and water for oxidation reaction to obtain a mixed solution;
[0023] (2) Mix the mixed solution obtained in the step (1) with the structure-directing agent, and perform a hydrothermal reaction to obtain an all-solid WO 3 / Tungsten mesh electrode material; the temperature of the hydrothermal reaction is 220-230° C., and the time of the hydrothermal reaction is 24-26 hours.
[0024] The invention mixes tungsten mesh, hydrogen peroxide and water to carry out oxidation reaction to obtain a mixed solution. The invention uses tungsten mesh and hydrogen peroxide as raw materials for oxidation reaction, generates tungsten ions and dissolves them in water.
[0025] In the present invention, the source of the tungsten mesh is not particularly limited, and commercially ava...
Embodiment 1
[0042] Cut the 100-mesh tungsten mesh into a cuboid with a size of 2cm×3cm×1mm (the mass of the tungsten mesh is 0.2g), clean it with acetone, ethanol and deionized water (ultrasonic frequency 60kHz) for 30 minutes, and finally blow it with the cold air of a hair dryer. Dry to get a clean tungsten mesh;
[0043] Place the above tungsten mesh in a beaker containing 30 mL of deionized water, and add 0.1 mL of H to the beaker 2 o 2 (The ratio of the quality of the tungsten mesh, the volume of hydrogen peroxide and the volume of water is 0.2g: 0.1mL: 30mL), with the frequency of 50kHz ultrasonic reaction 12min; Then add 0.0125g thioacetamide (thioacetamide and tungsten mesh The mass ratio is 0.0125:0.2), stirred at a rate of 600r / min for 35min, and then transferred to a Teflon-lined reactor for hydrothermal reaction at a reaction temperature of 220°C. After 25h of reaction, all-solid WO 3 / Tungsten mesh electrode material.
