Pulsed laser ablation in liquid (PLAL) method was used for nanocatalyst synthesis.
Graphite-encapsulated Fe (Fe@C) NPs were easily prepared by PLAL.
Methanol was used as both a carbon source and solvent for Fe@C NPs.
Fe@C/Pd NPs showed an enhanced degradation efficiency of m-DCB.
Fe@C/Pd NPs with 1.71 wt % of Pd showed an excellent dechlorination efficiency.
