초록/요약
The gas adsorption/desorption reaction that occurs on a solid surface forms the basic reaction of various catalysts and sensor devices. If the phases of various solids can be easily controlled in a limited elemental composition, a highly efficient device may be realized through an in-depth understanding of the adsorption and desorption reactions of gases occurring on the surface of the solid. We thus report the direct phase transformation of ReO3 nanorods into 2-dimensional(2D) nanosheets of ReS2 on carbon fibres (CNFs) using a reducing heat treatment and induction of a sufurization reaction. The gas sensing abilities for NO2 and H-2 were also explored in terms of the change of the electrical chracteristics for both 2D ReS2 nanosheets and ReO3 nanorods on CNFs.
