Figure 13. (A) Schematic of a Cu–single-atom Ru surface alloy catalyst with the dry reforming reactants and products shown on the left; (B) Stability of photocatalytic methane dry reforming reaction on a Cu-Ru catalyst under 19.2 W·cm^-2 white light illumination. The flow rates of CH₄ and CO₂ were both 8 sccm; (C) Intensity dependence of photocatalytic methane dry reforming reaction on Cu-Ru catalyst. No external heating was applied.
