Cobalt-based multicomponent nanoparticles supported on N-doped graphene as advanced cathodic catalyst for zinc–air batteries
文献摘要：
To improve the efficiency of cathodic oxygen reduction reaction (ORR) in zinc–air batteries (ZABs), an adsorption–complexation–calcination method was proposed to generate cobalt-based multicomponent nanoparticles comprising Co, Co3O4 and CoN, as well as numerous N heteroatoms, on graphene nanosheets (Co/Co3O4/CoN/NG). The Co/Co3O4/CoN nanoparticles with the size of less than 50 nm are homogeneously dispersed on N-doped graphene (NG) substrate, which greatly improve the catalytic behaviors for ORR. The results show that the half-wave potential is as high as 0.80 V vs. RHE and the limiting current density is 4.60 mA?cm?2, which are close to those of commercially available platinum/carbon (Pt/C) catalysts. Applying as cathodic catalyst for ZABs, the battery shows large specific capacity and open circuit voltage of 843.0 mAh?g?1 and 1.41 V, respectively. The excellent performance is attributed to the efficient two-dimensional struc-ture with high accessible surface area and the numerous multiple active sites provided by highly scattered Co/Co3O4/CoN particles and doped nitrogen on the carbon matrix.
