An overview of green methods for Fe2O3 nanoparticle synthesis and their applications

Nanoparticles received great attention during the last few decades due to their broad application in different fields. There are many conventional methods available, including physical and chemical techniques, for the fabrication of particles having a size in the range of nanometers; however, the green synthesis of these particles has received much interest because it reduces the use of harmful chemicals which are carcinogenic and costly. In this method the plant extract can be used in place of the harmful chemicals hence this method is considered as an ecofriendly low cost method. The present study evaluates the various available green synthesis methods for the fabrication of widely applicable inorganic Fe2O3 nanoparticles (NPs). This study also highlighted some potentially useful analytical techniques which were used for the characterization of the fabricated iron oxide nanoparticles. Moreover, this study also gives deep insight on the various applications including environment, energy storage, bio-medical etc. of the fabricated Fe2O3 NPs. This review is useful for designing and developing the Fe2O3 nanoparticles by green methods with potential applications.
