摘要

A series of Pd/N-doped graphene catalysts were designed for the efficient and highly selective synthesis of muscone through the hydrogenation of 3-methylcyclopentadecenone (XT). The catalysts were characterized using FT-IR, BET, XPS, XRD, Raman and SEM–EDS. All results indicated the uniform dispersion of Pd on NG. By optimizing reaction conditions, the hydrogenation of XT achieved a high yield and selectivity of muscone, producing a 99% yield at 2 MPa H2 and 90 °C in 10 h using a 10 wt% Pd/N-doped graphene catalyst functionalized with melamine (Pd/NmG), which significantly outperformed conventional Pd/C catalysts.
