Co3O4 nanorods with prevalent oxygen-vacancies confined by PDA-RGO nanosheets for excellent performances in supercapacitors

Jinjun Tian et al.

Summary: In this study, a Co3O4@polydopamine-reduced graphene oxide (Co3O4@PDA-RGO) nanocomposite was developed to alleviate deactivation issues in supercapacitors by self-reviving oxygen-vacancies (O(V)s) on transition metal oxides.
