Figure 6. (A) A graphic illustration for designing nanocarbon edge anchored high-density Pt₁ atoms for catalytic nitro compounds^[123]; (B) Side views of real space electron redistribution between graphene and GDY^[87]; (C) Schematic illustration of the proposed mechanism of 4-NP reduction catalyzed by Pd₁/GDY/G^[87]; (D) Schematic illustration for the construction of Pd₁/In₂O_3-x^[139]; (E) Schematic illustration of H₂ dissociation and H diffusion on Pt₁/Ni(111)^[148]; (F) Time courses of the conversion for Ni nanocrystals, Pt₁/Ni nanocrystals, Pt clusters/Ni nanocrystals, and Pt/C in selective hydrogenation of 3-nitrostyrene under 3 atm of H₂ at 40 °C^[148]. Pt₁: Single Pt atoms; GDY/G: graphite diacetylene/graphene; NP: nanoparticle.
