Figure 5. (a) The TOF_initial values for the dehydrogenation of FA at 298 K over Pd@NH₂-NC with different FA concentrations (The TOF_initial values at 20.0 M and 26.0 M were obtained when the conversion xa were 7.2 % and 2.7 %, respectively.); (b-c) Generated V(H₂ + CO₂) versus time for the dehydrogenation of FA at 298 K over Pd@NH₂-NC with (b) different Pd concentrations (inset: the corresponding logarithmic plot of the gas generation rate versus the Pd concentration) and (c) different temperatures; (d) The TOF values of different catalysts at different temperatures and (e) corresponding Arrhenius plots (ln k versus 1/T); (f) Comparisons of catalytic activity of Pd@NH₂-NC with other reported catalysts. TOF: turnover frequency; TOF_initial: initial turnover frequency.
