Abstract:
Pd/Fe bimetallic catalysts were synthesized by chemical deposition and used to dechlorination treatment of p-DCB. Batch experiments demonstrated that the Pd/Fe bimetallic particles can effectively dechlorinate p-DCB. Dechlorination efficiency accounted for more than 90% at Pd weight ratio (Pd to Fe) 0.02% and metal to solution ratio about 4g/74mL in 90min. Dechlorination ratios were affected by reaction temperature, initial pH, Pd ratio and the addition of Pd/Fe. Chlorobenzene represented stable partially dechlorinated intermediates in the generation of benzene.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
