In this paper, iron based bimetallic materials (Cu/Fe and Pd/Fe) were prepared and their reductive dehalogenation effects on bromoform was investigated. The reduction effect of Cu/Fe and Pd/Fe bimetal materials on bromoform will increase as the addition amount of bimetal increases; the presence of high concentration of H⁺ in the solution is conducive to the reduction; furthermore, the presence of dissolved oxygen has a inhibitory effect on reductive dehalogenation. The reductive dehalogenation between bimetallic materials and bromoform includes direct reduction and indirect reduction. Bimetallic materials achieved high performance because galvanic cells were created between Fe (serving as an anode) and plating elements (serving as a cathode). This structure enhanced the reducibility of iron for reductive dehalogenation by facilitating iron corrosion. The Pd/Fe system showed a better performance than Cu/Fe, which was attributed to a higher potential gradient that promoting the hydrogen production.
