Page 5123, Figure 4b,c and Supporting Information. It has come to our attention that Figure 4b,c and Figure S12 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 4b,c and Figure S12 are a little different from the originals. The data analysis and conclusions are not affected by the unintentional errors. The corrected Figure 4 is shown below. The complete corrected Supporting Information is also provided. Page 5124: In the discussion of Figure 4b,c, the text should be changed to agree with the corrected figure, as follows: “For PANI NDs and PANI/CoP HNWs, the H signal of −NH− can
