In this study, a novel catalyst has been prepared through supporting Pd nanoparticles (NPs) on the surface of boehmite (gamma-AlOOH) based hollow aluminosilicate microspheres (HAM@gamma-AlOOH). The prepared Pd/HAM@gamma-AlOOH catalyst has high catalytic activity for the hydrogenation of nitroarenes to their corresponding amino derivatives with high yields at ambient conditions. The high catalytic efficiency is attributed to the large pore size of the flower-like hierarchical flakes structure of HAM@gamma-AlOOH, that gives Pd NPs on the support surface easy accessibility. Moreover, the Pd/HAM@gamma-AlOOH catalyst can also be easily recycled at least five times without obvious decrease of catalytic activity. This work may provide a useful method for the fabrication of supported noble metal NP-based catalysts on the surface of mesoporous hierarchical structure materials with easy accessibility and superior activity.
