摘　　要：采用离子交换法合成了新型的杂多阴离子[CoW12O40]5-柱撑的水滑石[Mg2Al(OH)6]5[CoW12O40].26H2O.系统研究了以硝酸根型水滑石作为前体,通过插层组装制备杂多阴离子柱撑水滑石的反应条件及其控制规律,考察了杂多阴离子柱撑水滑石的组成、结构和性能之间的关系,通过XRD,FTIR等表征手段分别对杂多阴离子柱撑水滑石的晶相结构及其影响因素、红外光谱等进行了研究,并详细研究了光催化性能.A new heteropolyanion [ CoW12O40 ] 5- pillared hydrotalcite [ Mg2 Al（OH） 6 ] 5 [ CoW12 O40]· 26H2O was synthesized by ion - exchange method. The paper systematically studied the reaction conditions and control law of heteropolyanion pillared hydrotalcite which prepared by the intercalation assembly and with nitrate - based hydro- talcite as a precursor, investigated the relationships among composition, structure and performance of heteropolyanion pillared hydrotalcite. Through XRD, FTIR and other characterization methods, the paper studied the crystalline structure, influencing factors and infrared spectrum of heteropolyanion pillared hydrotalcite, and studied the photo- catalytic properties in detail.
