Abstract:
Immobilization of Pt-based nanoparticles on carbon support is of great significance in catalysis for their superior activity and enhanced durability. Herein, we report for the first time a feasible NaCl template-engaged approach to firmly immobilize PtNi nanoparticles into two-dimensional (2D) graphitic carbon nanosheets (denoted as PtNi@GCNs hereafter). The elaborate employment of the NaCl template regulates the formation of 2D graphitic carbon nanosheets, which tightly immobilize the in situ-generated PtNi nanoparticles. The smart integration of catalytically active PtNi nanoparticles with carbon nanosheets endows the as-prepared PtNi@GCNs with superior catalytic activity and outstanding stability toward the hydrogenation of 4-nitrophenol, making them a promising catalyst for environmental remediation. We believe that the present work can inspire the future design of carbon nanosheet-based nanohybrids with unique functionalities for diverse applications.

This experiment will demonstrate the hydrogenation of chalcone as an example of an alkene hydrogenation reaction (Figure 1). In this experiment, palladium on carbon (Pd/C) will be used as a heterogeneous catalyst for the process. A balloon will be used to supply the hydrogen atmosphere.
