Fig. 2: Deciphering plasmon-induced electron behavior via in situ NAP-XPS characterization.
From: Near-infrared-featured broadband CO2 reduction with water to hydrocarbons by surface plasmon
a and b In situ NAP-XPS spectra of Cu 2p3/2 (a) and contour plot for the amplified top view of the selected box-shaped area (b). c, d In situ NAP-XPS spectra of Pd 3d5/2 (c) and contour plot for the amplified top view of the selected box-shaped area (d). The in situ NAP-XPS data are recorded continuously for 1 h over Au rod@CuPd2 at 0.25 mbar CO2 atmosphere and light illumination is introduced into the catalytic system in the middle 30 min (marked in orange color). Representative peak positions are marked with open squares in (b) and (d). The squares and lines in black and white indicate unilluminated and illuminated conditions, respectively.
