The present invention discloses a kind of three-dimensional flower ball-shaped cadmium ferrite bismuth meal body and preparation method thereof, including：With Bi (NO 3 ) 3 ·5H 2 O, La (NO 3 ) 3 ·6H 2 O and Fe (NO 3 ) 3 ·9H 2 O is raw material, and square block Bi is prepared by hydro-thermal method 0.9 La 0.1 FeO 3 Powder, then processes Bi by a step etch 0.9 La 0.1 FeO 3 Powder, with DMF as solvent, while using reducing agent hydrazine hydrate and complexing agent methyl thioglycolate, preparing three-dimensional flower ball-shaped cadmium ferrite bismuth meal body.Flower ball-shaped Bi prepared by the present invention 0.9 La 0.1 FeO 3 Powder specific-surface area detection increases, while preparation method is simple, cycle is short, corrosion efficiency high, easy control of reaction system and non-environmental-pollution. |
