Comparative studies on adsorptive and photocatalytic potential of differently synthesized ferric oxide nanoparticles for malachite green

In the present work, effect of different fuels on the structural, morphological, magnetic, adsorptive and photocatalytic properties of ferric oxide nanoparticles (Fe2O3 NPs) was evaluated. Fe2O3 NPs were synthesized via combustion method by using oxalyl dihydrazide (ODH), polyethylene glycol (PEG) a...
