Abstract

A LMO-organic (LMO = layered metal oxide) hybrid precursor route has been developed to synthesize rectangular (WO3)n structures. In the present work, regular rectangular orthorhombic (WO3)n has been fabricated by a thermal decomposition of the as-synthesized rectangular [WO3(bpy)0.5]n (bpy = 4,4'-bipyridine) precursor, which is formed by a process of intercalation, coordination, and self-assembly using the hydrothermal treatment of (WO3)n and 4,4'-bipyridine. The precursor and final products were characterized by field-emission scanning electron microscopy, transmission electron microscopy, electron-induced X-ray fluorescence analysis, X-ray diffraction analysis, derivative thermogravimetry analysis, and thermogravimetric analysis.

摘要

已开发出一种层状金属氧化物-有机（LMO = 层状金属氧化物）混合前驱体路线来合成矩形（WO3）n结构。在本工作中，通过对合成的矩形[WO3（bpy）0.5]n（bpy = 4,4'-联吡啶）前驱体进行热分解制备出规则的矩形正交晶系（WO3）n，该前驱体是通过（WO3）n与4,4'-联吡啶的水热处理，经插层、配位和自组装过程形成的。通过场发射扫描电子显微镜、透射电子显微镜、电子诱导X射线荧光分析、X射线衍射分析、导数热重分析和热重分析对前驱体和最终产物进行了表征。
