Key words
double-atom catalyst - iron catalysis - cobalt catalysis - dehydrogenation - alcohols
Significance
An Fe–Co double-atom catalyst supported on N-doped carbon (FeCo-DAC), prepared according
to equation 1, catalyzed the dehydrogenation of alcohols to afford the corresponding
aldehydes or ketones in ≤98% yield with generation of H2 gas (eqs. 2 and 3).
Comment
FeCo-DAC was characterized by means of XRD, XPS, Raman, ICP-AES, TEM, HAADF-STEM,
EDX, XANES, and EXAFS analyses. In the dehydrogenation of benzyl alcohol, the catalytic
activity of FeCo-DAC was superior to that of the corresponding Fe and Co single-atom
catalysts or other supported metal catalysts, such as Pd/C or Ru/C.
