A Review on Plant Extract Mediated Green Synthesis of Zirconia Nanoparticles and Their Miscellaneous Applications

Development of reliable and environmentally gracious routes for the fabrication of metal oxide nano-particles is a crucial step in nanobiotechnology. Among the all zirconia nanoparticles (ZrO_2 NPs) draws more attention due to its significant biocompatible, electrical, mechanical, and optical properties. Many natural biomolecules in plant extracts such as alkaloids, amino acids, enzymes, proteins, polysaccharides, polyphenols, steroid, and vitamins could be involved in bioreduction, formation, and stabilization of ZrO_2 NPs. In the last decade, numerous efforts were made to develop ecofriendly methods of synthesis to avoid the hazardous byproducts. In this review, green synthesis of ZrO_2 NPs, their characterization techniques, and miscellaneous applications were discussed.
