Figure Lengend Snippet: Figure 1. Characterization of the working electrode (A) TEM images of the as-synthesized Cu composite. (B) SEM image of the as-prepared Cu gas-diffusion electrode (GDE) and inset image show the water contact angle at around 140. (C) In situ Raman spectroscopy monitoring the pre-reduction processes at various applied potentials in 1 M KHCO3 at 298 K. SHE means standard hydrogen electrode. (D) X-ray diffraction patterns of pristine Cu GDE and Cu GDE after reduction together with bare gas-diffusion layer (GDL). (E) XPS analysis of Cu 2p regions of the pristine Cu GDE and Cu GDE after reduction. (F) Auger emission spectra of Cu LMM region of the pristine Cu GDE and Cu GDE after reduction.

Article Snippet: The in situ surface-enhanced Raman spectroscopy was carried out using an inverted confocal Raman microscope (JASCO RMP-510) equipped with an He/Ne laser (532 nm).
