摘要	Cr2O3@WO3 and WO3 hierarchical nanostructures are prepared using a two-step water bath method, which just needs mild conditions and takes little time. The response to xylene of the Cr2O3@WO3-based sensor is much higher (about 4 times) than that of a WO3-based sensor, and both of the response and recovery processes are quick. As for the selectivity, the Cr2O3@WO3-based sensor shows a better response to xylene, while the WO3-based sensor shows a better response to ethanol. The reason for the response and selectivity change is considered to be that a heterostructure is formed between Cr2O3 (a P-type semiconductor) and WO3 (an N-type semiconductor). Moreover, Cr2O3 is reported to show catalytic oxidation of methyl groups.
