Metal–organic framework derived petal-like Co3O4@CoNi2S4 hybrid on carbon cloth with enhanced performance for supercapacitors

Starting from 2D Co-based metal-organic frameworks, novel petal-like core-shell Co₃O₄@CoNi₂S₄ nanowall arrays are synthesized on carbon cloth using a facile two-step method and investigated as promising electrode materials for supercapacitors.
