Carbon nanofibers anchored LZ-276 zeolite supported Pd-Cu bimetallic catalyst for Suzuki-Miyaura coupling reaction

Abstract

Herein, the composite catalyst supported by Pd-Cu bimetal was prepared by hydrothermal synthesis method using carbon nanofibers anchored LZ-276 zeolite as carrier. The addition of Cu not only save cost but also realize the high dispersion of metal nanoparticles. Under the optimized reaction conditions, the catalyst exhibits excellent catalytic activity and cycle stability in the Suzuki-Miyaura reaction. The designed structure effectively improves the catalytic performance of metal nanoparticles catalyzed reaction, and would inhibit the leaching or aggregation of metal particles. The strategy of reducing the noble metals dosage by using non-noble metals to replace noble metals reduces the catalyst costs, and thus holding great promise for industrial application.
