dc.description.abstractWe investigated the effect of grain size on the H-2-sensing behavior of SnO2-ZnO composite nanofibers. The 0.9SnO(2)-0.1ZnO composite nanofibers were calcined at 700 degrees C for various times to control the size of nanograins. A bifunctional sensing mechanism, which is related not only to the SnO2-SnO2 nanograins, but also to the ZnO-SnO2 nanograins with surface metallization effect, is responsible for the grain-oriented H-2-sensing properties and the selective improvement in sensing behavior to H-2 gas compared to other gases. Smaller grains are much more favorable for superior H-2 sensing in SnO2-ZnO composite nanofibers, which will be an important guideline for their use in H-2 sensors. The one-dimensional nanofiber-based structures in the present study will be efficient in maximizing the sensing capabilities by providing a larger amount of junctions.en_US
