In this research a series of metal oxides(SrO,La2O3,CaO,MgO,and Li2O)were loaded over Mg-spinels via a hybrid combustion-impregnation method.Nanocatalysts were characterized by XRD,FESEM,TEM,EDX,BET-BJH,and FTIR analyses.The XRD results showed the formation of pure crystalline phases in all of the nanocatalysts.Among all the nanocatalysts,the FESEM images and BET-BJH data displayed large pore diameters and high specific surface area for Li2O/MgAl2O4.Also,the overview of 3D surface analysis demonstrated the rough surface for this nanocatalyst,in which the RMS parameter was evaluated to be 16.5 nm.The as-prepared nanocatalysts were successfully employed in green biodiesel production from sunflower oil(MeOH/Oil = 12 molar,catalyst loading = 5 wt%,temperature = 110 ℃ and time = 3 h).The superior activity of about 98% was obtained with Li2O/MgAl2O4.The other remarkable outcome of this research was the reusability of Li2O/MgAl2O4 through 6 reaction cycles with fresh feed in the same operational conditions.
