Özet

Herein, we reported reductions of acid, amide, ester and ketone groups with selectivity (>99%) by the catalytic transfer hydrogenation of with CuPd alloy nanoparticles (NPs) decorated on mesoporous graphitic carbon nitride (Cu50Pd50/mpg-C3N4) catalyst under mild conditions in a water/methanol mixture. CuPd alloy NPs were synthesized by the co-reduction of palladium (II) acetylacetonate and copper(II) acetylacetonate in oleylamine (OAm) solution by the reduction of morpholine-borane solution and then assembled on mpg-C3N4 via liquid phase self-assembly method. The alpha,beta-unsaturated carbonyl compounds were obtained from the condensation reaction of the benzaldehyde derivatives with acetone derivatives. Cu50Pd50/mpg-C3N4 nanocatalyst was characterized by TEM, XRD, XPS, BET and ICP-MS. Cu50Pd50/mpg-C3N4 nanocatalyst is highly active catalyst for the reduction of various organic groups and converted to high yield and 99% selectivity. The superior Cu50Pd50/mpg-C3N4 nanocatalyst is highly efficient and reusable catalyst which is reuse after 5 cycle with 98% conversion. (C) 2021 Elsevier B.V. All rights reserved.
