Microwave-assisted Synthesis of MgFe2O4-ZnO Nanocomposite and Its Photo-catalyst Investigation in Methyl Orange Degradation
In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...

متن کاملSynthesis of Mn3O4-Based Aerogels and Their Lithium-Storage Abilities
Mn3O4 aerogels and their graphene nanosheet (GN) composite aerogels were synthesized by a simple supercritical-ethanol process. In the process, supercritical ethanol acted as a reductant to reduce graphene oxide and MnO2 gels simultaneously. The synthesized aerogels consisted of 10-20 nm Mn3O4 nanocrystallites, with BET-specific surface areas around 60 m(2)/g. The performance of the aerogels as...
متن کاملOne Step Rapid Synthesis of Nano-Crystalline ZnO by Microwave-Assisted Solution Combustion Method
In this study nano-crystalline ZnO particles were synthesized by microwave-assisted solution combustion method. Zinc nitrate and urea were used as oxidizer and fuel, respectively. The effect of fuel to oxidizer (F/O) ratio on ZnO powder properties was investigated by using different urea/nitrate ratios. X-ray diffractometer, scanning electron microscopy and fourier transform infra-red were used...
