Synthesis of ferrites using various parts of plants: a mini review

Abstract Ferrite nanoparticles are magnetic. They also show photocatalytic and antibacterial activities. These unique properties make them extremely useful for various applications e.g., they can potentially be used electronic equipment, telecommunication systems, radar, sensing material, catalytic applications, several biomedical applications. Several methods have been developed to synthesise these materials. include sol-gel, co-precipitation, ball-milling, combustion, hydrothermal heating, microwave procedure. Recently, materials using parts of plants. Hibiscus rosa-sinensis, Hydrangea paniculata , rosemary, nyctanthes arbor-tristis, sesame seed, aegle marmelos, Limonia acidissima juice, aloe vera, amaranthus blitum, ginger cardamom, were this purpose. Ferrites silver, cobalt, zinc, nickel prepared successfully. Few doped ferrites, silver cobalt ferrite, zinc ferrite synthesised. Use plant-parts evades the necessity use expensive metal salts. Various plants, flowers, leaves, seeds act as a gelling agent, chelating reducing capping agent during reactions. This is non-toxic, eco-friendly, cost-effective method. The samples characterized Advance Materials Characterisation Techniques. results very much in agreement with desired values. In few cases, better activities observed ferrites obtained via Left-over food fruits method which may help waste management. Still, tremendous scope left area that exploited scaling-up product.
