Embodiment 1
[0045] (1) Take about 500mL of fresh pig blood in a 1L beaker, heat and dry in a drying oven at 80°C until constant weight.
[0046] (2) Crush the dried fresh pig blood, pass through a 200-mesh sieve, and take about 1.00 g of the under-sieved powder into the corundum ark.
[0047] (3) Put the corundum ark in a tube furnace for high-temperature pyrolysis, at a heating rate of 10°C / min, high-temperature pyrolysis at 900°C for 60 minutes, and cool to room temperature.
[0048] (4) The pyrolyzed material was pulverized and fully washed with a large amount of mixed solution of deionized water and ethanol, and then freeze-dried (19Pa, -50°C) to obtain a catalyst.
[0049] (5) Electrocatalytic performance test: Weigh 9 mg of the prepared catalyst and a 2.0 mL centrifuge tube with an electronic balance, add 0.99 mL of absolute ethanol and 0.01 mL of 5% Nafion ethanol solution, and sonicate for 20 min-60 min to form a uniform dispersion. Take 10ul of dispersion liquid and drop-coat it...
Embodiment 2
[0052] (1) Take about 500mL of fresh pig blood in a 1L beaker to which 200mL of 50g / L sodium chloride solution has been added in advance, stir and let stand for 30min.
[0053] (2) Boil the pig blood after salting out in a 2.5L beaker with water for 20min, take it out and dry it at 80°C.
[0054] (3) Put the corundum ark in a tube furnace for high-temperature pyrolysis, at a heating rate of 10°C / min, high-temperature pyrolysis at 900°C for 60 minutes, and cool to room temperature.
[0055] (4) The pyrolyzed material was pulverized and fully washed with a large amount of mixed solution of deionized water and ethanol, and then freeze-dried (19Pa, -50°C) to obtain a catalyst.
[0056] (5) Electrocatalytic performance test: perform the performance test according to the method described in step 5 in Example 1, and the specific oxygen reduction catalytic performance is as follows figure 2 As shown, the stability test as image 3 shown. At the same time, the electrocatalytic oxyg...
