(a) Waterfall plot of time-resolved spectra gathered from the reaction of 50.9 μM 1,1-DCE and 16.3 mM H2 on Pd/Au NSs, and individual scans at 12, 30, 41, and 100 min (b, c, d, and e, respectively) after injection of 1,1-DCE/H2 solution. (f) Waterfall plot of time-resolved spectra gathered from the reaction of 254 μM 1,1-DCE and 81.9 mM H2 on Pd/Au NSs, and individual scans at 12, 30, 41, and 100 min (g, h, i, and j, respectively) after injection of 1,1-DCE/H2 solution.
