Embodiment 1
[0059] After the commercial carbon cloth was hydrothermally reacted in 69wt% concentrated nitric acid at 90°C for 2 hours, it was first washed with deionized water, then ultrasonically cleaned with acetone, alcohol, and deionized water for 15 minutes, and then heated in air at 60°C. Dry for 8h; KMnO 4 Dissolve in deionized water and stir well to obtain K + A solution with a concentration of 0.0005 mol / L, soak the pretreated carbon cloth in the solution for 2 hours, and then conduct a hydrothermal reaction at 85°C for 2.5 hours, then wash with deionized water, and dry at 60°C in the air for 8 hours to obtain a carbon cloth Loaded manganese-containing precursor; the KMnO 4 and IrCl 3 Dissolve in deionized water and stir evenly to obtain K + and Ir 3+ The concentrations were 0.001 mol / L and 0.00025 mol / L mixed solution respectively, the above-mentioned dried carbon cloth loaded with manganese precursor was immersed in the mixed solution for 2 h, then hydrothermally reacted at...
