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.
合成了纳米级钯/铁双金属颗粒，并用于对2,4-二氯苯酚进行加氢脱氯。2,4-二氯苯酚转化为苯酚，同时生成少量的2-氯苯酚和4-氯苯酚。已确定了每一步的反应途径和反应速率常数。研究了双金属中不同钯负载量、温度和pH条件对2,4-二氯苯酚加氢脱氯的影响。结果表明，较高的钯负载量、较高的温度和弱酸条件有利于2,4-二氯苯酚的催化脱氯。
