A double-jet electrospinning method was adopted to fabricate In2O3/Co3O4 nanofibers (NFs). The sensitivity of In2O3/Co3O4 NFs and In2O3 NFs were compared and analyzed, and the morphology, structure, chemical composition, and gas-sensing properties of the samples were comprehensively characterized. The results show that the introduction of Co3O4 can...
