In recent years, spinel-type structural cobalt salts (NiCo2O4, CuCo2O4, etc.) have been widely used electrocatalysis because of their superior properties such as large crustal reserves, low cost, environmental friendliness, high electrochemical activity, abundant oxidation valence, and stable chemical properties. this paper, hollow carbon nanofibers loaded CuCo2O4 nanowires (CuCo2O4@CNFs) were ...

Abstract The electrolysis of water is one the most promising strategies to produce renewable fuels and it important develop an energy-conserving, low-cost easily prepared electrocatalyst for oxygen evolution reaction (OER). In this work, Ni foam supported Co 4 S 3 (Co /NF) was fabricated by a facile one-step approach at room temperature exhibited excellent OER performance in alkaline media. Spe...

A composite MnO2@MOF-5 is prepared by in situ incorporation of pre-synthesized MnO2 nanoparticles into metal organic framework, MOF-5, during synthesis. The product characterized powder X-ray diffraction analysis, Raman spectroscopy, Fourier transform infrared ultraviolet-visible scanning electron microscopy, energy-dispersive and elemental mapping, which support the formation proposed material...
