Correction: Ji et al. Mesoporous Cobalt Oxide (CoO_x) Nanowires with Different Aspect Ratios for High Performance Hybrid Supercapacitors. Nanomaterials 2023, 13, 749

There was an error in the original publication [1]. As the JCPDS Card 48-0083 is modified by new synchrotron X-ray powder diffraction data, the chemical composition and crystal structure of the CoO_x-130 precursor require modification in the published article. A correction has been made to Section 3. Results and Discussion, Paragraph 2:

“Multiple diffraction peaks indicate that the composition of the precursor is complex, but the main component is certainly Co₆(CO₃)₂(OH)₈·H₂O (JCPDS No.48–0083) [31]. Accordingly, the chemical reactions related to the precursors can be described as follows:

In the original publication [1], Bhojane, P.; Bail, A.; Shirage P. A quarter of a century after its synthesis and with >200 papers based on its use, Co(CO₃)0.5 30 (OH)·0.11H₂O proves to be Co₆(CO₃)₂ (OH)₈·H₂O from synchrotron powder diffraction data. Acta Crystallogr. C Struct. Chem. 2019, 75, 61–64. was not cited. The citation has now been inserted in Section 3. Results and Discussion, Paragraph 2, and replaced the original citation (ref. 31), Zhang, Z.; Hao, J.; Yang, W.; Lu, B.; Ke, X.; Zhang, B.; Tang, J. Porous Co₃O₄ Nanorods-Reduced Graphene Oxide with Intrinsic Peroxidase-Like Activity and Catalysis in the Degradation of Methylene Blue. ACS Appl. Mater. Interfaces 2013, 5, 3809–3815.

Following the above, there was a mistake in Figure S1 of the original publication [1].

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
