Embodiment 1
[0033] A method for preparing a kaolin-based three-dimensional particle electrode, comprising the following steps:
[0034] (1) Grinding: First, grind the kaolin with a ball mill, then use a mortar to grind the kaolin into a finer powder as much as possible, pass through a 100-mesh molecular sieve, place it in a constant temperature drying oven at 80°C, and dry it to a constant weight; Subsequently, grind the black algae with a ball mill, and then use a mortar to grind the kaolin into a finer powder, pass through an 80-mesh molecular sieve, and place it in a constant temperature drying oven at 120°C to dry and set a constant weight;
[0035] (2) Mix molding: get 0.7446g (0.5wt% Fe) ferrous sulfate heptahydrate and 0.5859g (0.5wt% Cu) copper sulfate pentahydrate to be dissolved in 20mL deionized water, 18g kaolin powder after pretreatment and Put 12g of black algae powder into the mixture of ferrous sulfate heptahydrate and copper sulfate pentahydrate, impregnate and adsorb for...
