NiPd Nanoparticles on Nanoporous Carbon Embedded in\nGraphitic Carbon Nitride for Transfer Hydrogenation and Suzuki–Miyaura\nCoupling Reactions

Doping\nheterogeneous atoms and tuning the electronic metal–support\ninteractions (EMSI) are effective ways to modulate the catalytic performance\nof supported Pd nanocatalysts. Herein, we report a facile way of enhancing\nthe catalytic efficiency of Pd atoms by alloying with excess Ni atoms\nand simultaneously immobilizing them in a nitrogen rich framework\nthat was fabricated from graphitic carbon nitride and nitrogen-doped\ncarbon (NiPd/g-C<sub>3</sub>N<sub>4</sub>–C). The immobilized\nNi<sub>90</sub>Pd<sub>10</sub> NPs on g-C<sub>3</sub>N<sub>4</sub>–C is found to be an excellent catalyst for hydride transfer\nand C<sub>sp<sub>2</sub></sub>–C<sub>sp<sub>2</sub></sub> bond\nforming reactions, and the enhanced activity of the NiPd is attributed\nto electronic perturbations that modify the electronic states of the\nPd and improve their catalytic properties due to the Ni alloying and\nEMSI, as evidenced by X-ray absorption spectroscopic analysis.
