摘要
用Triton X-100/正己醇/环己烷/盐溶液的四元反相微乳液体系制备了纳米四水羟基硝酸氧铋((Bi6O4(OH)4)(NO3)6(H2O)4),研究了不同比例Triton X-100、正己醇、环己烷对微乳液体系的影响,绘制了反相微乳液体系的拟三元相图,确定了室温下微乳液法制取纳米四水羟基硝酸氧铋的最佳条件,制备出了棒状和片状两种产物,利用TEM、IR、XRD、TG-DSC等手段对产物的结构和性能进行了表征。
The Nano-sized bismuth oxide nitrate hydroxide hydrate （（Bi6O4 （OH）4） （NO3）6 （ H2O）4 ） was prepared by chemical reaction of bismuth nitrate and ammonia by a reverse microemulsion method, which used cyclohexane as the oil phase, Triton X-100 as surfactant phase, and n-hexanol as co-surfactant phase. In this paper, different amounts of n-hexanol as a co-emulsifier and cyclohexane as oil respectively, were used to systematically investigate their effects on the microemulsion region in the quasi-ternary phase diagram of the system studied. Rodlike and plate-form bismuth oxide nitrate hydroxide hydrate nanoparticles were obtained. The product was characterized by infrared spectra, transmission electron microscopy, X-ray powder diffraction and TG-DSC.
