摘要：

Herein, we have developed a facile one-pot PEG-200-assited hydrothermal method for the controlled-synthesis of highly dispersed hollow Fe3O4 nanoparticles (similar to 150 nm in diameter, similar to 25 nm in wall-thickness). Magnetic domains of hollow Fe3O4 nanoparticles are relatively regular with domain width of similar to 150 nm. The capacity of hollow Fe3O4 nanoparticles retained 599 mA h g(-1) after 50 cycles at 85 mA h g(-1). When returning to the initial rate of 100 mA h g(-1), the hollow Fe3O4 nanoparticles electrode returns a lower capacity (315 mA h g(-1)) than the original capacity (433 mA h g(-1)).
