Carbon-supported Ternary Nanocatalyst Palladium-Vanadium-Cobalt for Hydrodechlorination of 2,4-Dichlorophenol

Abstract

M ultimetallic nanocatalysts have remarkably revealed activities in various catalytic applications. Herein, the ternary nanocatalysts based on palladium-vanadium-cobalt were successfully synthesized through the reduction of their salts with the combination of sodium borohydride and ethylene glycol as reducing agents, including impregnating of activated carbon (AC) substrate with colloid solution of metallic nanoparticles (PdVCo/C). The immobile of trimetallic PdVCo on AC was evidenced by XRD, EDX analysis, transmission electron microscopy (TEM) and specific surface area (BET). Therein, TEM imaging showed that the PdVCo particles size is about 7 nm. The trimetallic nanocatalysts were evaluated in the hydrodechlorination of dichlorinated substrates which was defined by GC (FID detector). The obtained result was that the conversion of 2,4-dichlorophenol was over 91% in the case of PdVCo nano-catalyst in the presence of potassium hydroxide and the high catalytic stability was observed.
