Ultrafine alpha-Fe2O3 nanoparticles with an average size of-3 nm were successfully prepared by a facile reverse micro-emulsion method. As-prepared alpha-Fe2O3 nanoparticles exhibited excellent gas sensing activity due to its size and surface effect. These ultrafine and highly monodisepersive alpha-Fe2O3 nanoparticles (UHFN) showed fast response, high selectivity and good stability to acetone vapor. This kind of material is expected to be a prospecting candidate for the application in acetone sensors. (C) 2016 Elsevier B.V. All rights reserved.
