Ni3S2 NTs-CFs (2495 cm−1) is ∼40 cm−1 red shifted compared with that of Ni3S2 NTs-CFs (2535 cm−1).”

Page 615: Figure 5b and Supporting Information. It has come to our attention that Figure 5b, Figure S12, and Figure S14 were not correct. We resynthesized and remeasured the relative samples to make sure the accuracy of results. Due to the previous errors in the experimental operations and data processing, the corrected Figure 5b, Figure S12, and Figure S14 are a little different from the originals. The data analysis and conclusions are not affected by the unintentional errors. The corrected Figure 5 is shown below. The complete corrected Supporting Information is available. Page 616: In the text discussion of Figure 5b, the numbers should be changed to agree with the corrected figure, as follows: “After HER reaction at the potential of −250 mV vs RHE for 10 h, a peak at ∼2535 cm−1 is detected for Ni3S2 NTs-CFs, and a peak at ∼2495 cm−1 is seen for Cu NDs/Ni3S2 NTs-CFs. [...] It is worth noting that the Raman shift of S−Hads for Cu NDs/
