Templated synthesis of spinel cobaltite MCo2O4 (M=Ni, Co and Mn) hierarchical nanofibers for high performance supercapacitors

Rational construction of transitional metal oxides electrode materials with suitable structure and composition is an effective strategy of improving their electrochemical performance. Herein, novel MCo2O4 hierarchical nanofibers (H-MCo2O4NFs, M = Ni, Co and Mn) were fabricated by a multi-step self-templating method using electrospun nanofibers as precursors. Benefiting from the unique structure, such as numerous of vertically interlinked...
