Abstract Nanofibers of ZnO-SnO 2 nanocomposites doped with Au crystals were synthesized
by an electrospinning method for enhancement of H 2 S gas sensing performance. The …

The development of nanomaterial-based gas sensors has led to demanding research
interest in the last few decades due to their potential for high sensitivity, selectivity, and fast …

We investigated the effect of grain size on the H2-sensing behavior of SnO2-ZnO composite
nanofibers. The 0.9 SnO2-0.1 ZnO composite nanofibers were calcined at 700° C for various …

Gas sensors have been wildly used in various fields related to people's lives. Gas sensor
materials were the core factors that affected the performances of various gas sensors, and …

There is an increasing need for the development of low-cost and highly sensitive gas
sensors for environmental, commercial, and industrial applications in various areas, such as …
