以木质素磷酸酯季铵盐为模板剂直接沉淀法制备氧化锌介孔材料

Synthesis of mesoporous ZnO by direct precipitation with Lignin-phosphate quaternary ammonium salt

中文摘要英文摘要

本文以木质素基表面活性剂(木质素磷酸酯季铵盐,LPAS)为结构导向剂,采用溶液法一步反应制备了介孔氧化锌。XRD分析表明该氧化锌具有六方纤维矿结构,粒径在20-40nm。SEM和TEM分析表明LPAS浓度不同,所合成的氧化锌形貌不同;同时所制备的氧化锌中有大量的介孔存在,BET测试其平均孔径为36nm。

In this paper,Mesoporous-ZnO crystals were prepared in aqueous solutions with Lignin-based surfactant(Lignin-phosphate quaternary ammonium salt,LPAS) by one step. X-ray diffraction(XRD) studies show that fine hexagonal wurtzite ZnO particles can be obtained with diameter of 20-40nm. SEM studies reveal that different concentrations of LPAS can affect the Morphology of ZnO. The ball particles can be obtained by low concentration of LPAS. TEM give the evidence that mosopores are found in ZnO crystals and with the average pore size of 36nm according to the Brunauer-Emmett-Teller (BET) measurement.
