摘要：
A new type of nonspherical yolk-shell structures in the case of SnO2 has been successfully prepared by a simple anneal-etching strategy without employing any additional templates or capping agents. The morphological and structural characterization reveals that SnO2 yolk-shell particles have a hierarchical architecture with penetrable multi-walled surfaces and cuboctahedral shape, where the secondary building blocks are numerous nanoparticles. The synthetic step-dependent evolution process of SnO2 yolk-shell cuboctahedra is investigated and the possible formation mechanism is also discussed. To demonstrate the merit of unique structure for the fast mass transfer, sensor based on SnO2 products has been fabricated and the results exhibit excellent sensing performances for toluene detection. It is found that our SnO2 yolk-shell structures have a response of 28.6-20 ppm toluene at the optimal working temperature of 250 degrees C, and the response time and recovery time are within 1.8 and 4.1 s, respectively.
