Abstract
Correction for ‘A 3D petal-like Ni3S2/CoNi2S4 hybrid grown on Ni foam as a binder-free electrode for energy storage’ by Fangshuai Chen et al., Sustainable Energy Fuels, 2018, 2, 1791–1798.
The authors wish to correct Fig. 2 of the manuscript and the corresponding explanation in the text.
Fig. 2 should appear as follows:
 | ||
| Fig. 1 XRD patterns of the NCN-2 samples (a) and XPS spectra of Co 2p (b), Ni 2p (c) and S 2p (d). | ||
The section of text beginning with the sentence “In the Fig. 2c…” should read:
“In the Fig. 2c, the XPS spectra of Ni 2p can be well matched with two shakeup satellites and two spin–orbit doublets characteristic of Ni2+/Ni3+ using Gaussian fitting. As shown in Ni 2p XPS, the binding energies of Ni 2p peaks at ca. 855.4 and 875.0 eV are ascribed to Ni2+, and peaks at 857.9 and 876.5 eV to Ni3+ correspondingly. In the Fig. 2d, the S 2p XPS spectra can be fitted into a main peak and a shakeup satellite peak, in which the peak at 162.0 eV is ascribed to the binding energy of Ni–S and Co–S bonds.”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
