Embodiment 1
[0024] A method for preparing a porous carbon bioelectrode, comprising the following steps:
[0025] 1), first 80mL of nonionic surfactant Tween is added to 100mL of demineralized water to make a solution, and the demineralized water is configured by mixing absolute ethanol and deionized water in a volume ratio of 1:8;
[0026] 2), then 0.312g phloroglucinol and 0.5725g 5-hydroxymethylfurfural were added to the above solution and mixed evenly, after stirring for 10min, 0.1335g catalyst ferric chloride was added to carry out solution prepolymerization;
[0027] 3), put the above-mentioned prepolymerized solution into a mortar, add 23.2mL of dodecane dropwise, and emulsify manually with a pestle;
[0028] 4), put the viscous emulsion synthesized by emulsification in step 3) at 130°C for 24 hours, then extract and wash with ethanol, and dry in an oven at a drying temperature of 80°C until the water content is below 5%. The dried solid material was put into a crucible, and then t...
