[ 1 ] - Microwave-assisted rapid synthesis of Co3O4 nanorods from CoC2O4.2H2O nanorods and its application in photocatalytic degradation of methylene blue under visible light irradiation

In this work, Co3O4 nanorods were successfully prepared by microwave-assisted solid state decomposition of rod-like CoC2O4.2H2O precursor within a very short reaction time (6 min) without the use of a solvent/surfactant and complicated equipment. The as-obtained Co3O4 nanorods were fully characterized by X-ray diffract...

[ 2 ] - Low-cost and eco-friendly phyto-synthesis of Silver nanoparticles by using grapes fruit extract and study of antibacterial and catalytic effects

In this research, silver nanoparticles (Ag NPs) were prepared by a low-cost, rapid, simple and ecofriendly approach using Grape fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-...

[ 3 ] - [Co(NH3)5(NO3)](NO3)2 as an energetic coordination precursor for the preparation of Co3O4 nanoparticles at low temperature

In this paper, an energetic coordination compound namely pentamminenitratocobalt(III) nitrate, [Co(NH3)5(NO3)](NO3)2, was used as a new precursor for the preparation of Co3O4 nanoparticles. The results showed that the complex is easily decomposed into the Co3O4 nanoparticles at low temperature (200 °C) without employing a surfactant or solvent and any complicated equipment. The product was char...

[ 4 ] - Graphene Oxide/Hydroxyapatite/Silver (rGO/HAP/Ag) nanocomposite: Synthesis, characterization, catalytic and antibacterial activity

In this paper, a novel ternary nanocomposite namely reduced graphene oxide/hydroxyapatite/silver (rGO/HAP/Ag) was prepared by a simple hydrothermal method using graphene oxide nanosheets, Ca(NO3)2, (NH4)2HPO4, and AgNO3 as starting materials. The as-prepared nanocomposite was characterized by using various photophysical techniqu...
