Fig. 6

The red color represents the hydrogenation of C≡C bonds to corresponding C=C, and the ratio within brackets for the internal alkyne substrates indicates the cis/trans ratio of alkene products. aReaction condition: 10 mL of ethanol, 40 °C, 1 bar H2, and 1000 rpm. 1 mmol substrate, 0.028 mol% Pd. b60 °C. c80 °C, 0.084 mol% Pd. d0.056 mol% Pd, 1 Mpa H2. e 0.056 mol% Pt. Detailed characterizations of Pt1/MoWO3 are provided in Supplementary Fig. 55-57.
