WebIncreased attention has been paid to the synthesis of hematite nanoparticles recently due to its properties and application in various fields of modern technology. ... In this study nanopowder of a-Fe 2 O 3 (hematite) were synthesized by controlled precipitation method in three stages: precipitation of precursors, washing and calcination. WebHematite nanoparticles have been shown as effective and inexpensive materials for sensors, catalysts, energy storage, and environment indicators [70–72]. Recently, hematite nanoparticles have also been verified to be an operative adsorbent for heavy and toxic metals from water [73].
