Synthesis of single-crystalline α-Fe2O3 nanobelts via a facile PEG-200 assisted solution route

Abstract

A facile PEG-200 assisted solution route for the synthesis of single-crystalline α-Fe₂O₃ nanobelts (20–40 nm in width, hundreds of nanometres in length) at 85 °C for 30 min has been developed. Electrochemical studies indicate the synthesized α-Fe₂O₃ nanobelts exhibit excellent discharge and charge capacities of 1068 mAh g⁻¹ and 701 mAh g⁻¹, which allow them to be a potential candidate for capacitor application.
