Cd-doped SnO2-reduced Graphene Oxide Composite Nanofibrous Mats as CO Gas Sensors
Abbas Mobasheri,Saeed Parhoodeh,Gholamabbas Shams 한국섬유공학회 2022 Fibers and polymers Vol.23 No.3
In this study, SnO2 nanofibers and their modifications (Cd doping and making a composite with reduced grapheneoxide) were synthesized via electrospinning and employed as CO gas sensing. The enhanced sensing properties of Cd-dopedSnO2-RGO nanofibrous mat comparing to other counterparts could be ascribed to p-type behavior of RGO inside thenanofibers and catalytic activity and adding new sites for oxidation of cadmium elements, which offered flexible andoptimum gas sensing. These mats had a specific surface area of 74.56 m2/g with 10.65 nm cylindrical slender channels andaverage fiber diameter of 200.57 nm.
