•Variety low-dimensional nano architectures were reported in the field of WO3 via hydrothermal process.•A growth mechanism is proposed based on comparative studies.•Nanosheets-like WO3 hierarchical architectures showed the excellent properties
WO3H2O with different morphologies were synthesized through hydrothermal method by adding different surfactants. The effect of surfactants on tailing morphology was investigated through XRD and SEM analyses in detail and the possible formation mechanism was discussed. Furthermore, the gas-sensing performances of obtained samples to ethanol were investigated. The results revealed that the WO3H2O with the hierarchical architectures assembled by nanosheets shows the highest response to ethanol among four kinds of the nanostructures WO3. These results on the preparation, mechanism and gas sensing properties of WO3H2O nanostructures hold great potential for the syntheses of oxide materials with novel nanostructures and their applications.
Graphical abstractIn this work, we prepare various kinds of WO3 low-dimensional architectures via a simple hydrothermal process, and report their growth formation mechanism and gas sensing properties.Figure optionsDownload full-size imageDownload as PowerPoint slide
