Highly Effective Electrochemical Water Splitting with Enhanced Electron Transfer between Ni2Co Layered Double Hydroxide Nanosheets Dispersed on Carbon Substrate

“…In Co 2p , the peak values of binding energy at 780.5 eV and 796.2 eV correspond to Co 3+ , and the binding energies at 782.3 eV and 796.6 eV belong to Co 2+ . The appearance of Co 3+ may be caused by the effect of oxygen in solution on the sample at high temperature [23][24][25][26]. The distribution of C in XPS data was roughly as follows: C-C 284.9 eV, C=O 288.3 eV, C-O 287.5 eV (as shown in Figure S1).…”

“…The diffraction peaks of samples at 11.1 • , 35.4 • , and 48.9 • are different from those of (003), (012), and (110), respectively. After loading with silk fibroin, diffraction peaks corresponding to the (003), (012), and (110) crystal planes of the sample still exist, and there are obvious diffraction peaks corresponding to silk fibroin at 31.2 • and 52.5 • , indicating that Ni 2 Co-LDH was successfully loaded onto the silk and increased the layer spacing of LDH [23,24]. To understand the chemical valence states of each element in Ni 2 Co−LDH@C, the XPS of Ni 2 Co-LDH@C is given in Figure 2.…”
