Three-dimensional Pyrenyl Graphdiyne Supported Pd Nanoparticle as an Efficient and Easily Recyclable Catalyst for Reduction of 4-Nitrophenol
The fabrication of highly active and easily recyclable Pd-based catalyst is meaningful for their practical application.Herein,a Pd-based dip-catalyst(Pd@Pyr-GDY)is fabricated on graphdiyne(Pyr-GDY)grown on copper foam,and applied in the reduction of nitroarenes.Specially,the as-formed Pd@Pyr-GDY shows good catalytic performance toward the reduction of 4-nitrophenol(4-NP)to 4-aminophenol(4-AP)by NaBH4 with a rate constant k value of 3.84 min^(−1),which is 12-fold higher than that of the commercial Pd/C.More importantly,Pd@Pyr-GDY could be easily and rapidly recovery from the reaction medium and no distinct inactivation was found after six cycles of the reaction.This work presents an easy way to design an efficient and easily recyclable Pd-based catalyst for practical use.
