英文摘要	Considering the specific surface area, flexible structures, high porosity, and a homogeneous and isotropic nature down to the atomic scale possessed by the amorphous nanostructure, an interesting controlled dehydration route has been developed to synthesize the crystalline/amorphous core/shell (C/A-C/S) MoO3 nanocomposite, in which macroisopolyanion [Mo36O112(H2O)(16)](8-) ({Mo-36}) was successfully assembled into a one-dimensional connection and underwent a deficient crystallization induced by the prospective infiltrative dehydration process. The as-obtained MoO3 samples' affirmative composition and composite structure have been further demonstrated by the XRD, TEM, HRTEM, and Raman spectra measurements. As a result of this special C/A-C/S structure, the MoO3 composite exhibited high selectivity and a higher sensor response, at a lower working temperature (180 degrees C) to ethanol gas compared with other ID MoO3 micro/nanostructures reported previously.; Chemistry, Multidisciplinary; Crystallography; Materials Science, Multidisciplinary; SCI(E); EI; 7; ARTICLE; gaopeng@hrbeu.edu.cn; chenyujin@hrbeu.edu.cn; yangpiaoping@hrbeu.edu.cn; 2; 569-575; 14
