Embodiment 1
[0040] A carbon / nickel oxide / nickel patterned microelectrode manufacturing process, comprising the following steps:
[0041] 1. Synthesis of hollow nickel oxide nanospheres:
[0042] 1) Dissolve 0.8 g of glucose in 80 mL of deionized water in a beaker, and stir to obtain a transparent solution; dropwise add 1M sodium hydroxide solution therein, adjust the pH to 8, and obtain a mixed solution I;
[0043] 2) Heat the mixed liquid I in a water bath to 80°C for 3 hours, and transfer it to the inner lining of a polytetrafluoroethylene high-temperature and high-pressure reactor with a capacity of 100mL, assemble the inner lining of the high-temperature and high-pressure reactor with the outer stainless steel lining, and then place Heat and keep it in an oven at 180°C for 5h, then wash the obtained reaction product I (multiple washes with a mixed solution of deionized water and absolute ethanol), centrifuge and dry (dry at 60°C for 12h), to obtain a solid product I;
