Acetone Sensing Properties of A Gas Sensor Based on SnO2/ZnO Composite Hetero na

Hollow hierarchical SnO2 nanofibers was synthesized by electrospinning, then ZnO nanorods grew on SnO2 nanofibers in the zinc acetate solution in the water bath with constant temperature of 90 C ̊. SnO2/ZnO composite hetero-nanofibers was obtained by electrospinning and hydro-thermal method. The morp
