Synthesis of uniform octahedral tungsten trioxide by RF induction thermal plasma and its application in gas sensing

Well-defined uniform octahedral WO3 are prepared via a simple one-step thermal plasma technique. The detailed structures of the synthesized materials are characterized by XRD, EDX, FESEM, SAED and HRTEM. Each octahedron is nearly perfect with a highly sym

通过一种简单的一步热等离子体技术制备出了定义明确的均匀八面体三氧化钨。利用X射线衍射（XRD）、能谱分析（EDX）、场发射扫描电子显微镜（FESEM）、选区电子衍射（SAED）和高分辨率透射电子显微镜（HRTEM）对合成材料的详细结构进行了表征。每个八面体近乎完美，具有高度的对称性。
