A Green Protocol for Synthesis of MAl_2O_4, [M = Cu and Co] Spinels Under Microwave Irradiation Method

摘要

Nanosized metal aluminates MAl_2O_4, [M = Cu and Co] are synthesized from their nitrates solution by using pomegranate peel extract as fuel in microwave combustion. MAl_2O_4 [M = Cu and Co] nanoparticles are grown in microwave assisted synthesis followed by annealing at 700°C. The nanoparticles have been characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), UV-VIS spectroscopy and photoluminescence (PL) spectroscopy. The PXRD analysis has confirmed their spinel composition. The green protocol and microwave combustion route for spinel synthesis are rapid, simple, without any hazardous chemicals as reducing or stabilizing agents and economical.
