Novel ZnO multi-layer architectures have been prepared successfully by using poly (sodium 4-styrenesulfonate) (PSS) as structure-directing agent through hydrothermal route The mass ratio of reactants (Zn(CH3COO)(2) 2H(2)O and PSS) plays a critical role on the synthesis of ZnO with different structures The as-prepared multi-layer architectures are hexagonal profiles and consist of many nanosheets with a 120 angle The thickness of these nanosheets can be controlled by the mass ratio of reactants The gas sensing properties of the as-synthesized ZnO multi-layer architectures are investigated in detail The results indicate that the obtained products exhibit superior response to acetone and ethanol as well as faster response/recovery times and good reprodu
