Abstract

Preparation of nano-rod aluminosilicate Mazzit (MAZ) zeolite under low-cost and environmental-friendly route is attractive, but still challenging. Herein, we report a green route for synthesizing nano-rod MAZ zeolite (MAZ-N) using low-cost and environmental-friendly choline chloride as template. Various characterizations including powder X-ray diffraction (XRD), scanning electron microscope (SEM), N sorption, and thermogravimetry-differential thermal analysis (TG-DTA) show that MAZ-N samples have good crystallinity and uniform porous structures. Furthermore, the crystallization process and impact of synthesis conditions of MAZ-N samples have been investigated in detail. These results suggest the potential applications of MAZ-N zeolites as supporting catalyst compounds in industrial processes.

摘要

以低成本且环境友好的方式制备纳米棒状硅铝酸盐菱沸石（MAZ）具有吸引力，但仍具有挑战性。在此，我们报道了一种绿色路线，使用低成本且环境友好的氯化胆碱作为模板来合成纳米棒状MAZ沸石（MAZ-N）。包括粉末X射线衍射（XRD）、扫描电子显微镜（SEM）、N吸附以及热重-差热分析（TG-DTA）在内的各种表征表明，MAZ-N样品具有良好的结晶度和均匀的多孔结构。此外，还详细研究了MAZ-N样品的结晶过程和合成条件的影响。这些结果表明MAZ-N沸石作为工业过程中负载型催化剂化合物的潜在应用。
