Catalytic hydrodechlorination of 2,4-dichlorophenol over nanoscale Pd/Fe: reaction pathway and some experimental parameters.
Nanoscale Pd/Fe bimetallic particles were synthesized and used to hydrodechlorinate 2,4-dichlorophenol. 2,4-dichlorophenol was transformed to phenol with a small amount of 2-chlorophenol and 4-chlorophenol produced. The reaction pathway and reaction rate constants for each step have been determined. The effects of various Pd bulk loadings in the bi-metals, temperatures and pH conditions on the hydrodechlorination of 2,4-dichlorophenol were examined. The results showed that higher Pd bulk loadings, higher temperatures and weak acid conditions are beneficial to the catalytic dechlorination of 2,4-dichlorophenol.
