作者张茂林(2019)在《基于砷钼酸盐有机—无机杂化材料的合成及性质研究》一文中研究指出:以砷为杂原子的杂多钼酸盐是一类重要的多酸化合物,它不仅具有新颖、复杂的拓扑结构,还具有优异的理化特性,其中可逆的多电子氧化还原能力、热稳定性和分子导电能力,使该类材料在电催化、光催化以及储能和电极材料制作方面具有广泛的潜在应用。目前有关钼酸盐的报道较少,储能性质研究也是刚刚起步。因此本文以简单的无机物为原料,选用合适的有机配体,通过控制溶液不同的pH,利用水热方法合成了2种{As2Mo6}和6种Well-Dawson{As2Mo18}型杂化功能材料。通过元素组成分析和单晶X-射线衍射确定其分子式为:[FeⅢNa(Hptp)2(As2Mo6O26)](1),[{CuⅠ(pyr)2}6(As2Mo6O26)]·H2O(2),(H2bipd)3[As2ⅢAs2VMo18O62]·3H2O(3),(H2biyb)3(As2Mo18O62)(4),(H4bib)2(H2bpy)2[(As2Mo18O62)]2·5H2O(5),(Hbiz)3(biz)9[As3Ⅲ(As2Mo18O62)2)]·2H2O(6),{Na2(H2O)4[As2Ⅲ(As2VMo18O62)]}·H2O(7),{Ag(trz)2}3[{Ag(trz)2}3(As2Mo18O62)]·H2O(8),(ptp=4’-(3,5-pyrimidine)-2,2’:6’,2’-tripyridine;pyr=pyrazole;bipd=2,5-bis(1-imidazolv)pyridine;biyb=1,4-Bis(imidazol-l-ylmethyl)benze;bpy=4,4′-bipyridine;bib=1,4-Bis(1,2,4-triazol-1-yl)hexane;biz=benzimidazole;trz=1,2,4-triazole)晶体结构分析表明:化合物1是由独特的三核配合物连接单元{FeNa2(Hptp)2}拓展成的二维层状的{As2Mo6}衍生物,其中复杂配体ptp是2,2′-联吡啶和嘧啶配体通过原位合成而形成的;化合物2是由双的{Cu(pyr)2}配合物桥连单元和{As2Mo6}多酸簇交替相连而形成的具有新拓扑结构{26·448·612}{2}6的2,12-连接的三维开放骨架,其代表最高连接的{As2Mo6}基有机-无机杂化材料;化合物3是由双质子化的bipd修饰的双砷帽Dawson超分子化合物;化合物4是由双质子化的biyb拓展的超分子三维网络;化合物5是两种不同的质子化的有机配体修饰的三砷帽Dawson型超分子衍生物;化合物6是由三个质子化的Hbiz有机配体和九个质子化的biz有机配体以及两个晶格水构成的零维Dawson型砷钼酸盐;化合物7是由一个对称双砷帽的Dawson结构单元和四个Na2(H2O)4连接单元构成的二维Dawson结构单元;化合物8是由Ag、1,2,4-triazole相连形成的三维Dawson型砷钼酸盐。化合物1-8均表现出双重电催化作用,既能催化还原无机的亚硝酸盐(NO2-)又能催化氧化生物有机分子多巴胺(DA),是极具前景的双功能传感材料。首次对化合物1-8进行了超级电容器性能的研究,实验结果表明{As2Mo6}和{As2Mo18}型砷钼酸盐有机-无机杂化材料作为超级电容器电极的活性物质展现出了较好的电极活性、较高的比电容以及较好的循环稳定性,是一个具有开发价值与应用前景的超级电容器电极材料。化合物1-8在紫外光照射下对亚甲基蓝(MB)、罗丹明B(RhB)两种染料的降解展现出优良的活性。八种化合物对MB和RhB的降解都达到了90%以上。其中三维高连接砷钼酸盐的催化效果远远要比零维同类化合物降解效果好,这说明金属有机配体的键入以及结构中的孔道有利于催化过程中的电子传递。
