Abstract

Abstract A facile and cost-efficient hydrothermal and lyophilization two-step strategy has been developed to prepare three-dimensional (3D) SnO2/rGO composites as NO2 gas sensor. In the present study, two different metal salt precursors (Sn2+ and Sn4+) were used to prepare the 3D porous composites. ...
