In the work, the group synthesizes carbon-encapsulated Fe3O4 nanocrystals via thermal decomposition of glucose on iron oxide nanocrystals. These configurations of iron oxides possess an amorphous carbon layer and ferrous state with high electronic conductivity, which offer enhanced electrochemical properties compared with pristine iron oxides.

Furthermore, this finding provides an effective solution for synthesizing complex metal oxide nanostructures, which could lead to a greater number of electronic or electrochemical applications for metal oxides.
