چکیده
Developing efficient oxygen reduction reaction (ORR) catalyst is essential for the practical application of Zn-air batteries (ZABs). In this contribution, we develop a novel zeolitic imidazolate framework (ZIF)-mediated strategy to anchor Co species on N-doped carbon nanorods ORR. Featuring ultrahigh N-doping (10.29 at.%), monodisperse nanocrystal decoration, and well-dispersed Co-Nx functionalization, obtained Co-decorated ([email protected]) exhibit decent ORR performance comparable commercial Pt/C in alkaline media. Aqueous ZABs have been assembled using [email protected] as cathode catalyst. The manifest high initial open-circuit voltage well energy density. addition, also demonstrates ideal quasi-solid-state ZABs.

Carbon-supported Pd-Co as cathode catalyst for APEMFCs and validation by DFT.
Carbon supported PdCo catalysts in varying atomic ratios of Pd to Co, namely 1 : 1, 2 : 1 and 3 : 1, were prepared. The oxygen reduction reaction (ORR) was studied on commercial carbon-supported Pd and carbon-supported PdCo nanocatalysts in aqueous 0.1 M KOH solution with and without methanol. The structure, dispersion, electrochemical characterization and surface area of PdCo/C were determined...
متن کاملReduced graphene oxide anchoring CoFe2O4 nanoparticles as an effective catalyst for non-aqueous lithium-oxygen batteries.
CoFe2O4 nanoparticles were uniformly anchored on reduced graphene oxide by a facile solvothermal method. The obtained CoFe2O4/reduced graphene oxide (CoFe2O4/rGO) hybrid was employed as catalyst for Li-O2 batteries. It could effectively lower the ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) overpotentials of the batteries and deliver a large capacity of 12 235 mA h grGO(-...
متن کاملNovel chemical method for synthesis of LiV3O8 nanorods as cathode materials for lithium ion batteries
A novel method which is based on the hydrothermal reaction was employed to synthesize LiV3O8. First, the mixture solution of LiOH, V2O5, and NH4OH was subjected to the hydrothermal reaction. The hydrothermal treatment yielded a clear, homogeneous solution. The evaporation of this solution led to the formation of a precursor gel. The gel was then heated at different temperatures in the range of ...
