Fig. 8. The plasmonic photothermal catalytic DRM reaction over Cu–Ru surface alloy antenna-reactor plasmonic photocatalysts. (a) Reaction activity and long-term stability data for Cu–Ru catalysts with different Ru ratios for plasmonic photothermal catalytic DRM. (b) A comparison of the activity, stability, and selectivity of Cu19.8Ru0.2 under 19.2 W cm−2 white-light illumination and for thermocatalysis at a reaction temperature of 1000 K. (c) Calculated ground- and excited-state energy curves for CH4 and CH dehydrogenation over Cu and Cu–Ru, respectively.
