Embodiment 1
[0028] Add 0.0133 mol of commercial vanadium pentoxide and 0.04 mol of oxalic acid to 80 mL of distilled water, and stir at 80° C. until the solution turns blue and clear to obtain a vanadium oxalate solution. Add 15 mL of ethanol to 15 mL of vanadium oxalate solution, then add 1 mL of hydrogen peroxide, stir evenly and add to the hydrothermal kettle.
[0029] Soak a 1*3cm commercial carbon cloth in 10mL of acetone for 2 hours, ultrasonically clean it twice with ethanol and water, then dry it in a 70°C oven for 12 hours, then soak the carbon cloth in 20mL of concentrated nitric acid for 80 ℃ oil bath for 2h, 90℃ for 0.5h, 100℃ for 0.5h, 120℃ for 1h, wash with water and ethanol twice in sequence, and dry in a 70℃ drying oven for 12h to obtain activated carbon cloth , and then the activated carbon cloth (0.0265g) was also put into a hydrothermal kettle, and subjected to a hydrothermal reaction at 180° C. for 3 hours to obtain a carbon cloth with a vanadium oxide precursor.
