Ultra-small Pd Nanoparticles Supported on Porous g-C3N4 Nanosheet for Efficient Hydrogenation Reaction

Heterogeneous catalytic hydrogenation reactions are of great significance in chemical industry. In this work, ultrasmall Pd nanoparticles (NPs) supported on porous g-C 3 N 4 nanosheets (Pd/CN) have been prepared for efficient hydrogenation reactions. The special structure of the catalytic metal–semiconductor heterojunction not only stabilize the Pd NPs but also improve their electronic activation. In addition, the high surface area of Pd/CN provides a large numbers of adsorption sites for styrene and H 2 . As a result, the optimized Pd/CN-0.5 nanocomposites achieved 100% conversion of styrene in 60 min under mild conditions. Graphic Abstract
