SnO2 is widely used for ethanol-sensing applications due to its excellent physicochemical properties, low toxicity and high sensitivity. However it a challenge construct 3D-hierarchical structures with sub 5 nm primary grain particle, which the optimized size ethanol sensor. Herein, genetic tri-level hierarchical microstructures are synthesised by conversion of 3D SnS2 flowers assembled ultrath...

Nowadays, modern technology is demanding more efficient gas sensors for advanced applications [1]. Consequently, there is a considerable effort towards the goal of high performance gas sensors based on novel sensing materials. Since the first report of graphene, thin two-dimensional (2D) inorganic nanomaterials with atomic or molecular thicknesses have attracted great research interest for gas ...
