Hydrogenation-dechlorination to produce 2,3-dichloropyridine is important for the next-generation pesticides. In this work, we successfully synthesized porous carbon nanospheres supported CuPd alloy nanoparticles via a simple and efficient one-pot strategy. Furthermore, by adjusting the Cu/Pd ratio and carbonization temperature, the obtained Cu2Pd1@PCNs-500-H2O2 showed the highly catalytic activity for the hydrogenation-dechlorination of 2,3,6-trichloropyridine with a conversion rate of 70.1 % and selectivity of 71.2 %. The catalyst showed outstanding catalysis performance even after five cycles. This simple and rapid one-pot strategy provides a new approach for the large-scale synthesis of efficient heterogeneous catalysts and offers an effective solution for reducing the high costs associated with precious metals.
