Abstract
The influence of bismuth addition on the activity and selectivity of home-made supported palladium catalysts in the reaction of hydrodechlorination of 2,4-dichlorophenol to phenol was studied. Bimetallic Pd–Bi/Al 2 O 3 and Pd–Bi/SiO 2 catalysts, containing 5 wt.% of Pd and 1–5 wt.% of Bi, are characterized by high conversion of 2,4-dichlorophenol, which reaches about 100% at the end of the reaction run. However, the catalysts 5%Pd–8%Bi/SiO 2 and 5%Pd–8%Bi/Al 2 O 3 show considerably lower conversion (respectively, about 25% and 60%), but they are characterized by the highest selectivity towards phenol (respectively, about 95% and 60%). The stability of the chosen bimetallic catalyst 5%Pd–1%Bi/Al 2 O 3 is higher than that of the monometallic palladium catalyst. The XRD and ToF-SIMS studies proved the presence of intermetallic compounds BiPd and Bi 2 Pd, which probably modify the catalytic properties of Pd–Bi/support catalysts in hydrodechlorination of 2,4-dichlorophenol.
