Abstract : Environmental pollution is among the biggest challenges faced by the global society today. This is largely due to rapid urbanization and industrialization. As a result, more and more research focuses on alternative methods of remediating and preserving contaminated ecosystems. Among such techniques, nanomaterials have become an exciting and evolving area of study. One such nanomaterial that has been shown to play a key role in environmental remediation is metal oxide nanoparticles. Due to their unusual physicochemical properties, such as abundant surface-active sites, tailorable size and shape, and high chemical stability, metal oxide nanoparticles have continued to draw considerable attention. Several metal oxide nanoparticles have been synthesized over the last several decades via physical, chemical, and biological means and their uses have been studied in numerous environmental remediation techniques. Despite being used in various roles, metal oxide nanoparticles are commonly used as adsorbents, catalysts, or antimicrobial agents. This chapter briefly presents the various techniques of metal oxide nanoparticle synthesis, their mechanism of remediation with brief overview of most commonly used metal oxide nanoparticles, such as TiO 2 , ZnO, iron oxides, CuO, SnO 2 , and WO 3 .
