Ru-functionalized Ni-doped dual phases of ?/?-Fe2O3 nanosheets for an optimized acetone detection

Abstract Lately novel strategies to enhance the sensing properties on iron oxide have been proposed achieve high performance gas sensors for acetone detection. In this working report, synthesis of iron-glycerate (Fe-Gly) using glycerol combine with Fe 3+ is first presented. Depending thermal treatment, compound can evolve into ?-Fe 2 O 3 , ?/?-Fe and ?-Fe . shows better as far detection concerned. Using dual phases a fundamental building block, their were further improved Ni doping Ru nanoparticles functionalization. The response selectivity was ascribed synergistic effects unique nanosheets, mixed phases, rich oxygen vacancies excellent catalytic activity nanoparticles. Graphical abstract
