| Abstract: | The Co3O4/C catalyst with nanoparticles was synthesized by a liquid control precipitation method.X-ray diffraction and transmission electron microscopy were used to characterize the structure and morphology of the catalyst.The electrocatalytic activity of the catalyst was investigated by line-scan voltammetry and cyclic voltammetry using rotating disk electrode technique.The results indicated that the Co3O4/C has electrocatalytic activity for the oxygen reduction reaction (ORR).The exchange current density ... |
