摘要: The graphenothermal reduction mechanism of Fe2O3 by graphene oxide (GO) is elucidated through careful experimental analysis. degree oxidation (DO) GO plays a key role in controlling the GO. with low DO follows conventional three-stage reaction path, i.e., ′2GO + → EG/Fe3O4 (Stage I) EG/FeO II) EG/Fe III)′ (where EG exfoliated reduced oxide), at temperatures 650 and 750 °C to reduce Fe2O3, whereas higher transforms rapidly ceases Stage I, formation °C. It also found that slow thermal treatment continues II further III depending on time heating temperature. (synthesized 550 °C, 5 h) using showed superior cycling performance as an anode Li-ion battery than its counterpart prepared (at from high owing good contacts between Fe3O4. ...
