a Comparison of the activity of BN-700, CeO2, and other BNs (AMBN, commercial bulk h-BN, and h-BN nanoparticles synthesized through ionothermal method) in acetylene hydrogenation at 150 °C. Error bars stand for standard deviations. b Acetylene semihydrogenation (at reaction temperature of 150 °C for 24 h) catalyzed by BN-700 with acetylene in ethylene (up) or only acetylene (bottom) as the feeding gas stream. c Arrhenius plots of the acetylene semihydrogenation with the apparent activation energy (Ea) for BN-700 and CeO2. d KIE measurement of BN-700 in acetylene semihydrogenation in the presence of H2 or D2. e HD light-off curves for BN-700 and CeO2. f Arrhenius plots of the hydrogen dissociation apparent activation energy (Ea) for BN-700 and CeO2.
