Highly dispersed rhodium atoms supported on defect-rich Co(OH) for the chemoselective hydrogenation of nitroarenes
Catalysts of 0.54% (Pt, Rh, Pd or Ru)/Co(OH) 2 and 1.23% Rh/Co(OH) 2 were successfully synthesized via simple hydrothermal and precipitation methods for the selective hydrogenation of nitroarenes. It was found that 0.54% Rh/Co(OH) 2 outperformed other catalysts, for example, 2-chloronitrobenzene hyd...

and 1.23% Rh/Co(OH)
2
were successfully synthesized
via
simple hydrothermal and precipitation methods for the selective hydrogenation of nitroarenes. It was found that 0.54% Rh/Co(OH)
2
outperformed other catalysts, for example, 2-chloronitrobenzene hydrogenation (with a turnover frequency (TOF) of 575 h
−1
) under 3.0 MPa H
2
at 100 °C for 1 h (much higher than that of 1.23% Rh/Co(OH)
2
; TOF, 398 h
−1
). Through characterization of the nanostructure (XRD, TEM, HRTEM, AC-STEM (spherical aberration-corrected scanning transmission electron microscopy), AC-STEM-EDX elemental mapping and line-scanning, H
2
-TPD,
etc.
), it was confirmed that Rh was dispersed in the form of single atoms and ultrasmall nanoclusters on Co(OH)
2
for 0.54% Rh/Co(OH)
2
. Moreover, 0.54% Rh/Co(OH)
2
also exhibited high selectivity for -NO
2
hydrogenation for other selected nitroarene substrates hydrogenation reactions. This was mainly attributed to the presence of Rh as single atoms or super tiny nanoclusters in 0.54% Rh/Co(OH)
2
, leading to a significant increase in the number of active sites, beneficial adsorption of the -NO
2
-group at defect-rich Co(OH)
2
, and an interfacial synergy effect of Rh-Co(OH)
2
, thus improving the catalytic performance.
0.54% Rh/Co(OH)
2
exhibited 100% selectivity for -NO
2
hydrogenation at >96% conversion for nitroarene hydrogenation. Its excellent catalytic performance is due to the interfacial effect of Rh-Co(OH)
2
and Rh in the form of single atoms and nanoclusters. |
