Preparation of Ni/MgOZrO2 nanocrystals by citrate sol-gel method

摘要

Ni/MgOZrO_2 nanocrystals were prepared by the citrate sol-gel method and characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and nitrogen adsorption methods. Results show that the powders prepared by calcination for 4 h at a temperature of 800 deg C have a particle size of 15 nm and possess a surface area of 145 m~2/g.
