摘要:The design of nanoscale materials with controlled size and morphology has stimulated considerable research efforts in seeking novel morphology-dependent physical properties and functions. Much attention was focused on the discoveries of hierarchical structures having at least two length scales, micro-and nanometer. 0D quantum dots and 1D nanowires have been widely synthesized through various approaches. Moreover, 2D nanostructures such as nanoplates composed of Ag, Au, Pd, AgI, LnF_3, Bi_2Te_3, BN, Co(OH)_2, In_2S_3, CdS, and ZnS have also been reported. Wurtzite ZnO is one of the key wide-band-gap (3.437 eV at 2 K) semiconductors, widely utilized in piezoelectric transducers, varistors, phosphors, sensors, solar cells, and transparent conducting films. Various ZnO morphologies, such as nanowires, nanobelts, nanobridges, nanonails, nanohelices, nanopropellers, tetrapods, and comb-like nanostructures, have been produced through various routes including metal-catalyzing growth, thermal evaporation, hydrothermal synthesis, and so on. In this communication, we demonstrate the preparation of porous ZnO nanoplates and present their gas-sensing properties to chlorobenzene and ethanol at different operating temperatures. The fabrication of porous architectures in nanoplates in the nanometer scale enables greater control of the local chemical environment, with potential applications in gas sensors, sorbents, carriers, and in other fields.
