The heavy metal ions in the wastewater were efficiently enriched and recovered by precipitation flotation method, and the recovered products were pyrolyzed to form lithium ion battery anode materials, which realized the effective utilization of heavy metal resources. A porous Cu-Fe metal-organic famework was synthesized by precipitation flotation product in this study. When treated as aself-template by pyrolysis of this Cu-Fe-MOF at 750℃ for 1.0 h in an air atmosphere, porous hollow CuFe2O4 and Fe2O3 composite oxides were prepared and tested as an anode material for lithium-ion batterys(LIBs). The results of electrochemical measurements demonstrated that the composite oxides released an initial discharge capacity of 1403.7 mAh g-1 at the current density of 100 mA g-1 and remain reversible capacity of 300.6 mAh▪g-1 after 50 cycles, together with superior cyclic stability and unique hollow interior structure, making it to be a promising anode material for LIBs.
