Room temperature interdigitated electrode acetone sensor based on SnO2-rGO hybrid composite

Metal oxide especially SnO2 has been highly appreciated as one of excellent sensing materials used in the realm of gas monitoring due to it�s low cost of production, ease of fabrication and high portability. However, low sensitivity and high operating temperature limits applications of SnO2 especi...
