A simple and effective approach has been developed to synthesize palladium nanosheets that were successfully employed by reducing the Pd salt precursor in N,N-dimethylformamide (DMF), cetyltrimethylammonium bromide (CTAB), citric acid and using various reducing agents of CO gas and tungsten hexacarbonyl (W(CO)6). It indicates to be a novel method for the synthesis, providing a cost effective and an efficient route for the Pd nanosheets’ synthesis. The prepared Pd nanosheets have been characterized by ultraviolet–visible spectroscopy (UV-vis), transmission electron microscope (TEM) and X-ray diffraction (XRD). The results showed those Pd nanosheets have been obtained with the average edge length of ~20-25 nm (using CO gas) and around ~20 nm (using W(CO)6). Thus, the method using W(CO)6 as a reducing agent could be an alternative the route to use CO gas for the synthesis of Pd nanosheets. Since, the synthesized Pd nanosheets with highly plasmonic and catalytic properties are potential materials for applications in photothermal therapy, biosensor, catalyst and so on in the current and in future.
