The　catalytic　hydrogenation　of　petroleum　resin　(PR)　is　an　efficient　process　to　produce　high-value-added　hydrogenated　PR　with　improved　performance　and　wide　applications.　Herein,　a　hierarchical　flower-like　NiCu/SiO2　bimetallic　catalyst　has　been　successfully　prepared　by　reducing　the　hierarchically　structured　NiCu　silicate　precursor　((Ni,Cu)(3)Si2O5(OH)(4))　and　applied　for　PR　hydrogenation.　The　generated　bimetallic　NiCu　alloy　nanoparticles　are　anchored　on　the　surface　of　the　intercrossed　silica　nanoplatelets,　constructing　a　unique　multilevel　NiCu/SiO2　superstructure.　Moreover,　the　addition　of　Cu　could　not　only　lower　the　reduction　temperature　of　Ni　species　but　also　provide　electrons　to　Ni　to　form　electron-rich　active　sites.　The　NiCu/SiO2　bimetallic　catalyst　exhibited　enhanced　catalytic　activity　and　stability　for　PR　hydrogenation.　The　hydrogenation　degrees　for　C5PR　and　C9PR　could　reach　up　to　94.9　and　96.3%,　respectively,　which　are　much　higher　than　those　catalyzed　by　the　catalyst　prepared　via　an　impregnation　method　(85.9　and　88.7%).　Such　notably　enhanced　performances　could　be　ascribed　to　the　synergistic　effect　between　Ni-Cu　bimetals　and　the　highly　porous　superstructure.　Our　findings　provide　guidance　for　the　design　and　synthesis　of　efficient　and　stable　bimetallic　nanocatalysts　for　PR　hydrogenation.
