▎ 摘　　要

Researchers have risen to envisage a great deal of potential of nanocomposites (NCs) and foresee a wide range of applications of ternary NCs (TNCs) in particular. The hybrid nanostructures with synergistic impact of metal, metal oxide, carbon containing and polymer nanoparticles (NPs) dispersed on RGO nanosheets, obtained from the convenient protocols (efficient, economical and eco-friendly - E3 approach) along with nontoxic nature have led to a wide range of benefits. Owing to their enormous applications, it is pertinent to review all remedial, sensing, biomedical, energy storage and conversion abilities for traversing furthermore and motivating future researchers. Their consolidated study majorly validates the gigantic role in safeguarding the environment along with their comprehensive efficiency in a spectrum of energy storage and conversion. Moreover, their utilization in sensors also makes them research targets for biomedical scientists exploring clinical investigations. Their significance ensures to construct a link between academic research and environmental sustainability.
