Figure 1. (a) TEM image of Cu96NW@Ag4NP hybrids; (b) HAADF-STEM image and the corresponding elemental mappings of one Cu96NW@ Ag4NP hybrid; (c) HRTEM image of one Cu96NW@Ag4NP hybrid & FFT diffractograms of regions I−III marked; (d) XRD patterns of Ag NPs, Cu NWs, and CuNW@AgNP hybrids; the marked region indicates a diffraction peak from Ag (111) planes (see Figure S5); (e) Cu 2p XPS spectra of CuNW@AgNP hybrids and Cu NWs; (f) XANES spectra of Cu96NW@Ag4NPs and Cu NWs.
Figure 3. (a) Potential-dependent operando Raman spectra measured on Cu96NW@Ag4NP hybrids. (b) Cu K-edge XANES spectra measured over time on Cu NWs and Cu96NW@Ag4NP hybrids at −0.75 V vs RHE. (c) Schematic illustration of the ESH of EVA to VYA over CuNW@AgNP hybrids.
