Nanosheet-assembled Zn2SnO4 hierarchical structure had been prepared by a hydrothermal method at 180 degrees C. Different structures such as hierarchical sphere and solid cube are obtained by using different surfactants. The sensor based on nanosheet-assembled Zn2SnO4 hierarchical structure materials outperforms many other hierarchical sphere and solid cube-like Zn2SnO4 materials in response to toluene detection. Close investigation revealed that the Zn2SnO4 nanosheet-based sensors exhibited fast response speed at 280 degrees C after 4 cycles as the sensing materials of gas sensor, indicating that the hierarchical compounds might have a promising future in the gas sensor application field.
