Extended Data Fig. 1: Screening of catalyst under different reaction conditions.
From: Acetylene hydrogenation to ethylene by water at low temperature on a Au/α-MoC catalyst
a,b, Reaction conditions: 30 mg catalyst, 80 °C, 3.2 MPa (CO/C2H2/Ar = 6:5:89), 15 ml H2O, 20 hours. c, In-situ catalytic cycle. Reaction conditions: 100 mg catalyst, 80 °C, 3.2 MPa (CO/C2H2/Ar = 6:5:89), 10 ml H2O. The reaction was cycled by charging new feed gas into the system without separating the catalyst and solution. TOF is calculated as specific mole rate of C2H4 production on per mole of Au. d, The reaction temperature and time were changed to 220 °C, and 2 hours with other conditions unchanged. e, ICP-OES results.1st and 5th mean the results after one or five cycles.
