Catalytic dechlorination of monochlorobenzene by Pd/Fe nanoparticles immobilized within a polymeric anion exchanger
In this study, Pd/Fe bimetallic nanoparticles were immobilized within a macroporous anion exchanger resin D201 through simultaneous NaBH(4) reduction of their chloride-complex precursors, and the properties of the resultant composite for monochlorobenzene (MCB) dechlorination were evaluated in terms of Pd loadings, solution pH. kinetics and cyclic runs. The pseudo-first order degradation rate of MCB was 0.0699 min(-1) including partial contribution of adsorption by D201 matrix. However, all MCB was eventually decholorinated to benzene. A rapid and complete dechlorination of MCB by Pd/Fe-D201 was observed within 5 cycles. No Pd dislodge was observed in the process of iron corrosion. The composition of Pd/Fe bimetallic nanoparticles with D201 showed good performance on stability and durability in clechlorination of MCB. (C) 2011 Elsevier B.V. All rights reserved.
