摘要：
alpha-Fe2O3 (Hematite) nanoparticles with average diameter of 90 nm were synthesized by a low-temperature hydrothermal method. They were characterized by XRD, TEM, FESEM and infrared spectrum. The electrochemical tests were conducted between 3.0 and 0.3 V windows at different current densities. The results exhibit the excellent electrochemical performance of the as-prepared alpha-Fe2O3 nanoparticles. (C) 2004 Elsevier B.V. All rights reserved.
