Synthesis of Y_2NiMnO_6 nanoparticles by ethylene glycol sol-gel method

摘要

Y_2NiMnO_6 nanoparticles were synthesized via an ethylene glycol sol-gel method. Differential scanning calorimetry, thermogravimetric, X-ray diffraction and environmental scanning electron microscopy were utilized to characterize precursors and derived powders. Single-phase Y_2NiMnO_6 nanoparticles were formed at 800°C for 2h. The analysis suggests that adding ethylene glycol can effectively suppress the formation of metal oxide and promote the formation of Y_2NiMnO_6. Compared to Polyvinyl alcohol, ethylene glycol is much better for the synthesis of Y_2NiMnO_6 via sol-gel method.
