Abstract: With the growing magnitude of environmental pollution, the focus on environmental remediation is also bound to increase and more so it becomes challenging task. With the advent of nanotechnology and the immense potential of nanomaterials, their role in cleaning the environment by efficiently removing the pollutants and biological contaminants becomes highly significant. This article is an overview of the nanoscaledzerovalentmetal (nZVm) particles in the field of various environmental contaminant remediation. Nanomaterials have given a new dimension to the environmental cleanup and have proved to be an effective alternative for site remediation. Among various other metals the potential of nanoscaledzerovalent iron(nZVI) in contaminant degradation has received considerable attention over the past decade and has been successfully utilized for the degradation of a wide range of pollutants including polyhalogenated compounds, chlorinated solvents, dyes, inorganic anions, heavy metals etc. Recent advances in exploring the potential of nZVI have led to modify them for enhanced stability and improved mobility. The high activity of nFeo is well preserved by stabilizing or supporting the particles either by another metal or by using some organic stabilizers. The bimetallic nanoparticles exhibit extraordinary reaction kinetics towards dehalogenation and thus decontamination processes. Stabilizers like carboxy methyl cellulose (CMC) and polyvinyl pyrrolidone (PVP) not only stabilized the nanoparticles but also result in the synthesis of smaller sized nanoparticles with higher surface area and greater efficiency.
