| 英文摘要 | Hierarchical urchin-like Co3O4/CoWO4 core/shell microspheres are fabricated using a hydrothermal ion exchange approach. Co3O4/CoWO4 microspheres are made using Co3O4 nanowires, which are then covered using thin CoWO4 nanosheets. Capture of cobalt ions from Co3O4 nanowires by the tungsten acid radical is responsible for the CoWO4 nanosheet covering. The gas sensing characteristics show that urchin-like Co3O4/CoWO4 core/shell microspheres-based sensors shows high response towards acetone vapor, which is larger than that of either Co3O4 or CoWO4. A possible gas sensing mechanism for the improved performance of Co3O4/CoWO4 core/shell microspheres-sensor is the formation of heterostructure, which modulates the hole accumulation layer of Co3O4. |
