a The H2/D2 isotopic study of CO hydrogenation catalyzed by the 0.5Zr/Ru catalyst. b In situ DRIFTs corresponding to the H2–D2 exchange. The as-obtained 0.5Zr/Ru and 0Zr/Ru were introduced into an in situ chamber and treated with H2 and D2 under ambient pressure at 50 °C for 30 min before recording. c HD signal during a H2→D2→H2 switch at room temperature over the 0.5Zr/Ru and 0Zr/Ru samples. d Schematic depiction of H2–D2 exchange experiments.
