Composite materials have emerged as new class of materials which presented unique and enhanced applications in the nanotechnology field. In this study, Cobalt oxide-manganese oxide composites have been prepared by chemical co-precipitation method. Cobalt oxide particles were first prepared and used as seeds for making composites with manganese oxide. These composites have been characterized by XRD, SEM, UV-Vis spectroscopy and FTIR. Characterization tools confirmed the formation of Manganese/Cobalt oxide composites. XRD results presented the diffraction peaks for cobalt oxide, manganese oxide and MnCo2O4 compounds. FTIR spectrum also indicated the formation of bonds between Mn, Co and O especially at 461 cm−1 shows MnCO2O4 bonding. These composite materials absorb visible light of wavelength 682 nm and can be used in light activated photocatalytic activity for the degradation of toxic dyes.
Nanoscience is a standout amongst the most significant innovative work action in the outskirt of current science. From most recent two decades the nanotechnology and nanoscience have increased more significance in the field of research because of the enormous scale applications. The present work audits crafted by various researchers for the planning of iron nanoparticles by various procedures. Iron is a standout amongst the richest and generally utilized components on earth. Iron nanoparticles have a tremendous potential for various applications including magnetic liquids, magnetic resonance imaging (MRI) differentiate operators, catalyst for carbon nanotube development, nickel-iron batteries, and impetuses and sorbents for natural remediation. The preparation of iron nanoparticles by different methods, pulsed plasma, chemical reduction, chemical vapour condensation, one-step reduction, Green synthesis and Biosynthesis, its advantage over other processes are described. In this review article attempt has been made to compare each process by categorizing them specifically.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
