【摘要】：無機層狀材料由于其獨特的層狀主體結(jié)構(gòu)以及層間離子的可交換性,可以使不同的有機分子通過離子交換進入層間而不改變其層狀結(jié)構(gòu),并且保證了較高的穩(wěn)定性。這些有機-無機插層復(fù)合材料在吸附、分離、電化學(xué)催化、化學(xué)傳感器和生物傳感器等方面體現(xiàn)出了良好的性能。本文以Bi2Sr Ta2O9、Li Nb Mo O6、Li Nb WO6和Li Ta WO6為主體材料,以水溶性金屬卟啉(Mn TMPy P和Fe TMPy P)和亞甲基藍(MB)為客體材料,合成插層復(fù)合材料并對其性質(zhì)進行表征與測試。本文主要內(nèi)容概括如下:1.利用高溫固相合成法制備了Bi2Sr Ta2O9、Li Nb Mo O6、Li Nb WO6和Li Ta WO6等主體材料,并通過XRD、IR和SEM等手段對其進行表征。2.采用客體-客體離子交換的方法將水溶性金屬卟啉(Mn TMPy P和Fe TMPy P)以及亞甲基藍(MB)成功插入到Bi2Sr Ta2O9、Li Nb Mo O6、Li Nb WO6和Li Ta WO6的層間。并用XRD、IR、UV-vis和SEM等手段對插層復(fù)合材料的結(jié)構(gòu)、形貌和性質(zhì)進行表征。3.采用簡單滴涂法制備Mn TMPy P-Sr Ta2O7/GCE、Fe TMPy P-Nb Mo O6/GCE、MB+-Nb WO6/GCE和MB+-Ta WO6/GCE修飾電極,利用循環(huán)伏安法和脈沖伏安法測試修飾電極在磷酸鹽緩沖溶液中對氧氣和抗壞血酸的電化學(xué)催化性能。結(jié)果顯示修飾電極存在良好的穩(wěn)定性,并且對氧氣的還原和抗壞血酸的氧化有明顯的催化作用。
[Abstract]:Because of its unique layered host structure and interlayer ion exchangeability, inorganic layered materials can make different organic molecules enter the interlayer without changing their layered structure through ion exchange. These organic-inorganic intercalation composites are adsorbed, separated and electrochemical catalyzed. Chemical sensors and biosensors showed good properties. In this paper, Bi2Sr Ta2O9 and Li NB MoO6 were used. Li NB WO6 and Li Ta WO6 were used as host materials and water soluble metalloporphyrins mn TMPy P and Fe TMPy P) and methylene blue blue MBs were used as guest materials. The intercalation composites were synthesized, characterized and tested. The main contents of this paper are summarized as follows: 1. Bi2Sr Ta2O9 LiNb MoO6 was prepared by high temperature solid state synthesis. The main materials, such as Li NB WO6 and Li Ta WO6, pass through XRD. Ir and SEM were used to characterize them. 2. Water soluble metalloporphyrins mn TMPy P and Fe TMPy P and methylene blue (mn TMPy P and Fe TMPy P) were characterized by the method of guest guest ion exchange. MBs successfully inserted into the Bi2Sr Ta2O9. The interlaminar structure of Li NB WO6 and Li Ta WO6 was studied by means of SEM and SEM. The morphology and properties were characterized. 3. Mn TMPy P-Sr Ta2O7 / GCE-Fe TMPy P-Nb Mo O 6 / GCE was prepared by simple drop coating method. MB NB WO6/GCE and MB Ta WO6/GCE modified electrodes. The electrochemical catalytic performance of modified electrode for oxygen and ascorbic acid in phosphate buffer solution was tested by cyclic voltammetry and pulse voltammetry. The results showed that the modified electrode had good stability. And it can catalyze the reduction of oxygen and oxidation of ascorbic acid.
