The spacing was small compared to usual LDH (Zn-Al-CO 3 ) of 0.76nm in the case of carbonate anion as the guest. Also, TG analysis indicated that the electrostatic force between the Zn-Mo layers and carbonate anions was larger than those of Zn-Al LDH. Certainly, the carbonate anions ...
采用共沉淀法以硝酸锌、硝酸铝、氯化钼和尿素为原料,制备出锌铝水滑石(Zn/Al-LDH)和锌钼水滑石(Zn/Mo-LDH),经煅烧得到衍生复合氧化物(LDO),采用再构筑法用己二酸、辛二酸、癸二酸对其进行改性.借助X-射线衍射仪(XRD)、红外吸收光谱仪(FTIR)、透射电子显微镜(TEM)和热重分析(TG)等手段对制得的样品进行了...

利用水热法合成了ZnNiAl层状双金属氢氧化物(NiAlZn-LDH)和ZnNiAl层状双金属氧化物(NiAlZn-LDO),用于高效吸附去除水中的污染物Mo(Ⅵ).研究表明,ZnNiAl-LDH层间富含CO 2-3阴离子,使得NiAlZn-LDH在吸附去除Mo(Ⅵ)方面明显优于NiAlZn-LDO.Mo(Ⅵ)的吸附量随溶液pH值的升高而减少,但在近中性pH值范围内表现出...
