“…Consistent with the activity trend and H 2 -microcalorimetric result, the Pt 1 /Fe 2 O 3 -500 has a much larger KIE than Pt 1 /Fe 2 O 3 -600 (6.55 vs. 2.03, Supplementary Table 7), suggesting that H 2 activation is more difficult for the Pt 1 /Fe 2 O 3 -500. It is noted that the KIE value obtained on the Pt 1 /Fe 2 O 3 -600 catalyst is comparable to those reported on noble metal NP catalysts 46,47 , suggesting that the surface reaction, rather than the hydrogen dissociation, is the RDS. In contrast, the similar large KIE to the Pt 1 /Fe 2 O 3 -500 was reported for Ag/Al 2 O 3 NPs as well as Pd 1 /TiO 2 SAC, both of which featured poor capability for hydrogen activation 19,48 .…”

“…Ph-NH chemisorbs near a chemisorbed hydrogen atom and then is desorbed from the surface as aniline. Presence of nitrene has been suggested by Jackson et al who studied hydrogenation of 2-, 3-and 4-nitro acetophenone to respective anilines [55,56].…”

“…Noble metal catalysts, such as Pt, , Pd, , and Rh, , are generally considered to have strong activity for catalytic hydrogenation. For example, the two-dimensional metallic Pd nanosheet catalysts showed high nitrobenzene conversion as well as high aniline selectivity under 50 °C and 1.0 MPa of H 2 .…”

“…8 The hydrogenation of nitroaromatics can be carried out in the gas or liquid phase, and developing highly efficient catalysts is the key to promote this process. 9−11 Noble metal catalysts, such as Pt, 12,13 Pd, 14,15 and Rh, 16,17 are generally considered to have strong activity for catalytic hydrogenation. For example, the two-dimensional metallic Pd nanosheet catalysts showed high nitrobenzene conversion as well as high aniline selectivity under 50 °C and 1.0 MPa of H 2 .…”
