摘要
以硝酸银AgNO_(3)、磷钼酸H_(3)P(Mo_(3)O_(10))_(4)·xH_(2)O以及有机配体2-(吡啶-3-基)-1H-咪唑-4,5-二羧酸为原料,利用水热合成方法合成了一个新型的三维无机框架。采用单晶X-射线衍射对其晶体结构进行了表征。测试结果表明,该化合物属于正交晶系,Cmcm空间群。晶胞参数a=8.326(5)A,b=22.699(5)A,c=25.222(5)A,V=5218(3)A^(3),Z=8,R_(1)=0.0285,wR_(2)=0.0590,电化学分析结果表明该化合物对亚硝酸盐的还原具有一定的电催化效果。光催化降解有机染料的结果显示,目标化合物对有机染料亚甲基蓝具有良好的光催化降解活性。
Under hydrothermal conditions,a novel three-dimensional inorganic framework was successfully prepared by utilizing AgNO_(3),H_(3)P(Mo_(3)O_(10))_(4)·xH_(2)O,2-(pyridin-3-yl)-1H-imidazole-4,5-dicarboxylate)as starting materials.The crystal structure of the compound was characterized by single crystal X-ray diffraction The results showed that the compound crystallizes in the rhombic system,space group Cmcm with a was 8.326(5)A,b was 22.699(5)A,c was 25.222(5)A,V was 5218(3)A^(3),Z was 8,R_(1) was 0.0285,wR_(2) was 0.0590.In addition,the electrochemical properties of the compound displayed better electrocatalytic activity toward the reduction of nitrite.The photocatalytic properties of the compound were studied.The results showed that it had good degradation efficiency for methylene blue.
