Advances in the Synthesis and Applications of Metal Oxide Nanoparticles: A Comprehensive Review

Metal oxide nanoparticles are metal oxide which have the particle size between 1-100nm. Metal oxide nanoparticles include the oxides of various metal such iron oxide, zinc oxide, cupric oxide, magnesium oxide, silver oxide, titanium oxide etc. The synthesis of metal oxide nanoparticles has been widely explored in recent times due to its wide applications. Metal oxide nanoparticles have been greatly exploited due its unique ability to remove various organic and inorganic pollutants from contaminated water. They also show anti-microbial activities against various disease -causing micro-organisms. Apart from this, they also find their applications in drug delivery, biosensing, electronic devices. Synthesis of metal oxide nanoparticles includes physical, chemical and biological method. Water pollution is a serious cause of concern of this century. Various methods have been developed for the purification of wastewater treatment. One of the most important application of metal oxide nanoparticles is their ability to remove various organic and inorganic pollutants from contaminated water. Metal oxide nanoparticles due to its high surface area acts as efficient catalyst and adsorbent. This properties of them make them an efficient source for the photocatalytic degradation and also adsorption of contaminants from contaminated water.
