The influence of the substitution of methanol in place of ethanol during the ultrasonic production of antimony sulfoiodide (SbSI) nanowires is presented. The new technology is faster and more efficient at temperatures greater than 314 K. The products were characterized by using techniques such as powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), optical diffuse reflection spectroscopy (DRS) and IR spectroscopy. The coexistence of Pna2(1) (ferroelectric) and Pnam (paraelectric) phases at 298 K was observed in the SbSI nanowires produced in methanol. The methanol decomposes during the sonication or due to the adsorption process on SbSI nanowires.
介绍了在超声制备硫碘锑（SbSI）纳米线过程中用甲醇替代乙醇的影响。新工艺在高于314 K的温度下更快且更高效。通过粉末X射线衍射（XRD）、扫描电子显微镜（SEM）、能量色散X射线分析（EDXA）、高分辨率透射电子显微镜（HRTEM）、选区电子衍射（SAED）、光学漫反射光谱（DRS）和红外光谱等技术对产物进行了表征。在甲醇中制备的SbSI纳米线中观察到在298 K时Pna2(1)（铁电）相和Pnam（顺电）相共存。甲醇在超声处理过程中或由于在SbSI纳米线上的吸附过程而分解。
