An environment-friendly oxidation–discount methodology was used to organize Pd/C hybrid nanocomposites (NCs) utilizing carbon as host and Pd nanoparticles (NPs) as floor loading, and sodium citrate was used as a decreasing agent. The buildings and morphologies of the Pd/C hybrid NCs have been characterised by X-ray diffraction, transmission (high-resolution) electron microscopy (TEM, HRTEM), X-ray photoelectron spectroscopy and so forth. The outcomes demonstrated that the Pd NPs have been deposited on the floor of the C sphere beads, and the Pd NPs have been homogeneous and monodispersed. The outcomes additionally indicated that the diameter of the Pd NPs was three ± zero.5 nm and the Pd/C NCs have been 197 ± 6.5 nm. As well as, the Pd/C NCs confirmed improved electrocatalytic exercise for formic acid oxidation compared with business Pd NPs by way of controlling the floor buildings. So, the environment-friendly preparation methodology supplied developmental path to manufacture every kind of steel/C hybrid NCs architectures.
