Morphology-controlled synthesis of NiCo2O4 nanoflowers on stainless steel substrates as high-performance supercapacitors

Morphology-controlled synthesis of NiCo2O4 nanoflowers on stainless steel substrates as high-performance supercapacitors

NiCo2O4 nanostructures were synthesized via a chemical bath deposition method on stainless steel substrate by employing nickel chloride, cobalt chloride and urea as the starting reactants, at 343 K to 373 K for 5 h without the assistance of any additives. The influence of deposition temperature on t...
