•Urchinlike hex-WO3 microstructures assembled by numerous nanorods were fabricated via hydrothermal process.•A growth mechanism is proposed based on comparative studies.•Urchinlike hex-WO3 microstructures showed the excellent gas sensing properties.
Novel urchinlike hexagonal WO3 microspheres have been fabricated by a facile hydrothermal method in the presence of K2SO4. Morphology analysis reveals that the as-synthesized WO3 microstructures are assembled by numerous one-dimensional nanorods. Based on comparative studies, a possible formation mechanism is proposed in detail. What’s more, gas-sensing measurement indicates that the well-defined urchinelike WO3 microspheres exhibit excellent gas sensing properties.
Graphical abstractIn this work, we prepare urchinlike hex-WO3 microspheres via a simple hydrothermal process, and report their growth formation mechanism and gas sensing properties.Figure optionsDownload full-size imageDownload as PowerPoint slide
