a In situ XRD patterns of the structural evolution from Ni3Zn to Ni3ZnC0.7 (black curve: 100 °C, other curves: 200 °C with prolonged times) under a 1.0 vol% C2H2/He atmosphere. b The reactivity corresponds to the structural evolution of Ni3Zn/oCNT catalyst under reaction conditions. c Conversion and selectivity of Ni3ZnC0.7/oCNT catalyst (5.0 mg) under various acetylene to hydrogen ratios. Error bars represent standard deviation of experimental data acquired from three times. d Stability test (4.5 vol% H2, 20.0 vol% C2H4, 0.5 vol% C2H2, helium as balance) of Ni/oCNT (15.0 mg) and Ni3ZnC0.7/oCNT (10.0 mg) catalysts. The solid and hollow symbols represent the acetylene conversion and the selectivity to ethylene.
