Phenylcarbazole-stabilized palladium catalysts for efficient acetylene hydrochlorination

Pd-based/SAC catalysts modified with 9-phenylcarbazole (PCz) achieved 99.9% C 2 H 2 conversion and over 99% VCM selectivity with minimal deactivation. PCz stabilized Pd( ii ) particles and enhanced catalytic efficiency, as confirmed by DFT simulations.
