Figure 5. (A) The synthesis method for the Pt₁-Fe₁/ND catalyst^[16]; Kinetics experiments of p-NB hydrogenation over Pt₁-Fe₁/ND and PtNP/ND catalysts: (B) H₂ reaction order; (C) KIE value; (D) p-NB reaction order; and (E) apparent activation energy for p-NB hydrogenation^[16]; (F) Structure of the FeCo-N-C^[120]; (G) Degradation performance of FeCo-N-C and control samples N-C, Fe-N-C and Co-N-C in PNP reduction^[120]. Pt₁: Single Pt atoms; p-NB: p-nitrobenzene; NP: nanoparticle; ND: nanodiamond; KIE: kinetic isotope effect.
