High acetone-sensing performance of bi-phase a-/g-Fe₂O₃ submicron flowers grown using an iron plateIron oxide nanostructures have been studied extensively because of their excellent magnetic, optical, electrical, and catalytic properties. This work introduces a simple process to synthesize directly bi-phase a-/g-Fe2O3 submicron flowers on a Fe foil in NH4OH. The flowers were assembled by using many nanoplates with an estimated thickness of 20...

Excellent photocatalytic activity of ternary Ag@WO3@rGO nanocomposites under solar simulation irradiationThe ternary nanocomposite of Ag@WO3@rGO was synthesized via a two-step hydrothermal method in which the binary composite of the Ag-doped WO3 (Ag@WO3) prepared by the 1st hydrothermal step was combined with the reduced graphene oxide (rGO) via the ultrasonic-assisted 2nd hydrothermal step. The composition with Ag and rGO helped to reduce the opti...
