From: Asymmetric Ru-In atomic pairs promote highly active and stable acetylene hydrochlorination
a C2H2 conversions of Ru–N–In/NC, RuN4/NC, InN4/NC and NC [Reaction conditions: T = 180 °C, P = ambient pressure, GHSV(C2H2) = 180 h−1, V(HCl)/V(C2H2) = 1.15]. The error bars indicate the standard deviations of three experimental measurements. b Comparison of TOF (molC2H2/molmetal/h) of Ru–N–In/NC with other Ru-based, non-noble metal and non-metal catalysts6,7,59,60,61,62,63,64,65,66,67. Note that all the obtained data are the same as our reaction conditions. The data are calculated at 180 °C, ~5% C2H2 conversion to eliminate the influence of internal and external diffusion. Each point was determined by an isolated test to eliminate the interference of catalyst deactivation. c Long-term catalytic performances of Ru–N–In/NC and RuN4/NC, and corresponding AC HAADF-STEM images for the used samples. [Reaction conditions: T = 180 °C, P = ambient pressure, Vcat = 1.2 mL, V(HCl)/V(C2H2) = 1.15, GHSV(C2H2) = 180 h−1.] d Comparison of long-term stability (TOS and deactivation rate) for Ru–N–In/NC with other recently reported catalysts.
