    摘要:

    采用共沉淀法制备二元氢氧化铜锌硝酸盐(CZL)和氢氧化镍锌硝酸盐(NZL),考察了pH和Cu/Zn(Ni/Zn)原料摩尔配比对其晶体结构的影响,并通过XRD、FTIR和TG-DTA对其结构和热稳定性进行表征。结果发现,NZL的热稳定性明显高于CZL。在此基础上,分别采用共沉淀和离子交换法制备阴离子十二烷基硫酸钠(DS)和两性十二烷基二甲基羧基甜菜碱(DCB)表面活性剂插层CZL和NZL插层材料,并采用XRD和FTIR表征其结构,结果表明,采用离子交换和共沉淀法均可合成晶型单一且结构完整的NZL-DS;采用共沉淀法可合成晶型单一的NZL-DCB结构;采用离子交换和共沉淀法均可合成两种晶型的CZL-DS,且离子交换法不能完全取代层间的NO3-;采用离子交换法不能合成NZL-DCB和CZL-DCB,这与DCB的带电性弱有关。

    Abstract:

    Layered copper/zinc hydroxide nitrate (CZL) and nickel/zinc hydroxide nitrate (NZL) was synthesized by co-precipitation methods. The effect of pH and raw material molar ratio on preparation was investigated and discussed. Powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetry and differential thermal analysis (TG-DTA) were used to characterize the structure and thermostability of CZL and NZL. The results showed that the thermostability of NZL was much higher than that of CZL. Furthermore, the sodium dodecyl sulfate (DS) and dodecyl dimethyl carboxylbetaine (DCB) intercalation into the gallery of CZL and NZL were synthesized by co-precipitation and ion-exchanged methods. The results found that NZL-DS with pure phase was obtained by both methods; NZL-DCB was only obtained by ion-exchanged method; CZL-DS with two different structures was obtained by both methods, wherein NO3- cannot be totally substituted by ion-exchanged method. Moreover, DCB intercalation into the gallery of NZL and CZL were not successfully prepared by ion-exchanged method due to weak electrical property of DCB.
