Summary: | The invention belongs to the technical field of ORR electrocatalysts, and discloses an efficient nitrogen-doped carbon nanotube oxygen reduction electrocatalyst and a preparation method thereof, and the preparation method comprises the following steps: preparing composite slurry of metal salt ions, ionic liquid and hollow microspheres; carrying out high-temperature calcination on the composite slurry in an argon-hydrogen mixed atmosphere furnace; carrying out acid pickling on the composite powder obtained after calcination to remove the silicon dioxide balls; repeatedly cleaning the powder subjected to acid treatment with deionized water, and then performing vacuum freeze drying; and testing the redox electrocatalytic activity of the powder. The obtained nitrogen-doped carbon nanotube powder has the characteristics of high porosity, high flux, high oxygen reduction electro-catalysis performance and the like, the preparation method is simple, and the nitrogen-doped carbon nanotube powder is suitable for an ele |
