文摘

Pd-doped CoB amorphous (PdCoB) samples were prepared by two different methods and used for the reductive dechlorination of chlorobenzenes. XRD and TEM analyses show that amorphous PdCoB catalyst prepared by precipitation-reduction possesses high dispersion with the average size of 8 nm. BET area is 45 m²/g, appreciably higher than that of metal promoting or undropped CoB catalysts reported in literature. High stable activity for hydrodechlorination of monochlorobenzene in aqueous solution at room temperature is observed, which is related to high dispersion of amorphous catalyst and the interaction between Pd, Co and B.
