Sn doped ZnO layered porous nanocrystals with hierarchical structures and modified surfaces for gas sensors

Sn doped ZnO layered porous nanocrystals (Sn-ZLPCs) were synthesized. Each Sn-ZLPC was constructed by multi-layers of ZnO nanosheet with a thickness of 10-20 nm, and each layer was constructed by nanopores and polycrystalline ZnO nanocrystals. They exhibited high sensing responses to toxic volatile organic compounds (VOCs).
