▎ 摘　　要

The environment-friendly and energy-efficient monodispersed carbon-based nanosystems for environment monitoring are always in colossal demand. The present work has come up with a novel reverse micro-emulsification route which is inherently safer, energy-efficient and toxicant free approach for synthesis of monodisperse palladium nanoparticles embedded RGO based nanoreactors (Pd@NrGO/GCE). In present system, Pd@NrGO/GCE are acting as nanoreactors by providing large surface areas for electrocatalysis of methylpar-athion and allowing the study of redox attributes at faster rates. The successful characterization was done using X-ray diffraction studies, Raman spectroscopy, field emission scanning electron microscopy, small angle X-ray scattering and high resolution transmission electron microscopy analysis. The electroanalytical response in the square wave anodic stripping voltammetry has been generated by the adsorption of MP followed by subsequent redox catalysis by Pd@NrGO/GCE. The homogeneous film fabrication was enabled by smooth spherical nano-structures imparting higher surface areas with small particle size. The sensor performance towards oxidation of MP poses wide linearity and a low limit of detection of 1.067 ngml-1 with successful application to real time analysis.
