Persistent organic pollutants (POPs) have concerned public due to their toxicity, bioaccumulation and persistency in the environment and human health. Bimetallic catalysts have recently appeared significant effect for the remediation of groundwater and sediment contaminated with chlorinated organic compounds. Fe nanoparticles were produced by pulsed Nd:YAG laser (1064nm, 10Hz, 7ns) ablating onto an Fe plate immersed in methanol with a reducing agent, ascorbic acid. The morphological and optical properties of Fe/C/Pd catalysts via PLAL were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Ultraviolet-visible spectroscopy (UV-Vis). Fe/C/Pd catalysts were used to the dechlorination of 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (4,4'-DDT) under various conditions. The products of dechlorination reactions were analyzed by gas chromatography (GC). This study suggested that Fe/C/Pd catalysts could be potentially employed to rapidly degrade 4,4’-DDT in the contaminated environment.
