In　this　work,　a　stable　and　recyclable　Pd　catalyst　supported　on　N-containing　silane　coupling　agent　modified　silica　hollow　microspheres　with　macroporous　shells　(Pd/N-SHMs)　was　successfully　prepared　and　used　for　the　selective　hydrogenation　of　nitrile-butadiene　rubber　(NBR)　with　enhanced　catalytic　performance.　The　results　showed　that　Pd/N-SHMs　possessed　small-sized　and　well-dispersed　Pd　nanoparticles　(NPs)　and　the　macroporous　shells　were　beneficial　for　the　diffusion　of　macromolecular　NBR,　and　thus　with　such　a　catalyst,　the　reaction　could　occur　under　mild　conditions　and　high　hydrogenation　degree　(96.6%)　with　100%　selectivity　to　C=C　was　obtained.　The　prepared　catalyst　could　be　easily　recycled　and　reused　with　a　high　efficiency.　More　importantly,　because　of　the　strong　coordination　between　Pd　and　diamine　ligands,　Pd　NPs　could　be　anchored　steadily　over　the　support　and　only　5.0　ppm　Pd　residues　was　detected　in　products.　This　reaction　was　considered　as　pseudo-first　order　at　high　H-2　pressures,　and　the　reaction　activation　energy　was　calculated　to　be　as　low　as　18.1　kJ/mol.　Our　contribution　is　to　provide　an　efficient　and　recyclable　supported　Pd　catalyst,　which　may　promote　the　development　of　heterogeneous　catalytic　systems　for　unsaturated　macromolecular　hydrogenation.
