Sensitive and selective acetone sensor based on Gd doped WO3/reduced graphene oxide nanocomposite

A sensitive and selective acetone sensor based on Gd doped WO3/reduced graphene oxide, a novel nanocomposite, has been reported in this paper. To begin with, pure and Gd-doped (2, 4, 6 and 8 mol%) WO3 nanostructures exhibiting nanoplate type morphology were synthesized using a room temperature simple acid precipitation method without use of any template or surfactant. The gas sensing measurements were performed on pure and Gd doped WO3...
