Construction of In2O3 hierarchical microstructures consisting of single crystalline octahedral particles and polycrystalline fibers for detection of low concentration HCHO†
Abstract
Tunable In2O3 hierarchical microstructures consisting of single crystalline octahedral particles and polycrystalline fibers have been synthesized by one-step electrospinning combined with a subsequent calcination process, in which their enhanced gas-sensing mechanism is mainly ascribed to the synergistic effect of two typical structural units.
