Embodiment 1
[0028] Preparation of 10%Py30%CoPc / C catalyst: Weigh 0.0300g cobalt phthalocyanine, 0.0100g pyridine and 0.0600g Vulcan XC-72R carbon powder and place them in an agate mortar. Then add 10ml of methanol of analytical grade and grind thoroughly until the methanol is completely volatilized. The agate mortar and the mixture contained therein were put into a vacuum oven at 40° C. for 1 h to be vacuum-dried to obtain the desired CoPc-Py / C catalyst, and the mass ratio of CoPc to Py was 3:1.
Embodiment 2
[0030] Preparation of 15%Py25%CoPc / C catalyst: Weigh 0.0250g cobalt phthalocyanine, 0.0150g pyridine and 0.0600g Vulcan XC-72R carbon powder and put them in an agate mortar. Then add 10ml of ethanol of analytical grade and grind thoroughly until the ethanol evaporates completely. The agate mortar and the mixture contained therein were put into a vacuum oven at 40° C. for 1 h to be vacuum-dried to obtain the desired CoPc-Py / C catalyst, and the mass ratio of CoPc to Py was 5:3.
Embodiment 3
[0032] Preparation of 20%Py20%CoPc / C catalyst: 0.0200g cobalt phthalocyanine, 0.0200g pyridine and 0.0600g Vulcan XC-72R carbon powder were weighed and placed in an agate mortar. Then add 10ml of methanol of analytical grade and grind thoroughly until the methanol is completely volatilized. Put the agate mortar and the mixture inside into a vacuum oven at 40° C. for 1 h in vacuum to obtain the desired CoPc-Py / C catalyst, and the mass ratio of CoPc to Py is 1:1.
