【摘要】：基于多酸的無(wú)機(jī)有機(jī)雜化物是由金屬配合物、有機(jī)配體或其陽(yáng)離子與多酸基本建筑塊構(gòu)筑而成,它結(jié)合了無(wú)機(jī)和有機(jī)兩部分的優(yōu)點(diǎn),因此在藥物、催化、光電磁等方面具有潛在的應(yīng)用價(jià)值。本論文選用MoCl5為鉬源,利用水熱合成的方法,成功得到了四個(gè)鉬八異構(gòu)體的多酸化合物。在引入1,10-菲Up啉配體和過(guò)渡金屬Co2+時(shí),利用NaOH或KOH堿性溶液調(diào)節(jié)pH值至7.0左右,即可得到兩個(gè)結(jié)構(gòu)獨(dú)特的金屬配合物修飾的鉬八異構(gòu)體化合物:[Co(phen)_3]2H4[NaO(H2O)(ι-Mo_8O_(26))]2·2H2O(1)——首個(gè)新型ι-型[Mo_8O_(26)]4-的二聚結(jié)構(gòu)化合物,其中兩單體之間由Na+相連;[Co(phen)_3]4H4[α-Mo_8O_(26)][β-Mo_8O_(26)]2[Mo_6O_(19)]Cl2·18H2O(2)——首個(gè)既包含有兩種不同構(gòu)型[Mo_8O_(26)]4-還包含[Mo_6O_(19)]2-的化合物。在只引入4,4′-聯(lián)吡啶配體時(shí),用NaOH水溶液調(diào)節(jié)pH值至5.0左右,即可得到另一化合物:(C10H10N2)2[β-Mo_8O_(26)](3);在引入1,10-菲Up啉配體和過(guò)渡金屬Ni2+時(shí),用NaOH水溶液調(diào)節(jié)pH值至7.0左右,即可得到化合物4:[Ni(phen)2]2(ξ-Mo_8O_(26))(4)我們對(duì)這四個(gè)化合物進(jìn)行了系列表征,發(fā)現(xiàn)它們均有較低的禁帶寬度,是潛在的寬帶隙半導(dǎo)體材料,所以對(duì)這四個(gè)化合物進(jìn)行了光降解染料的研究,發(fā)現(xiàn)化合物3和4對(duì)可見(jiàn)光均有很好的響應(yīng),證實(shí)它們是很有效的光催化劑。在可見(jiàn)光照射下,兩個(gè)化合物均能達(dá)到降解有機(jī)染料甲基橙的目的,而且表現(xiàn)出較高的光催化降解能力。
[Abstract]:Inorganic organic hybrids based on polyacids are constructed from metal complexes, organic ligands or their cations and polyacid basic building blocks, which combine the advantages of both inorganic and organic parts, so in medicine, catalysis, Optoelectronic magnetism has potential application value. In this paper, MoCl5 was selected as molybdenum source, and four polyacid compounds of molybdenum octaisomer were successfully obtained by hydrothermal synthesis. The pH value was adjusted to about 7.0 by using NaOH or Koh alkaline solution when the 1 ~ (10) -phenanthroline ligands and transition metal (Co _ 2) were introduced. Two molybdenum octaisomers with unique structure were obtained: [Co (phen) 3] 2H 4 [NaO (H _ 2O) (l -Mo _ 8O _ (26)] 22 H _ 2O (1), the first new type [Mo _ 8O _ (26)] _ 4 dimer structure compound, The two monomers are connected by Na; [Co (phen) 3] 4H _ 4 [偽 -Mos _ 8O _ (26)] [尾 -Mo _ 8O _ (26)] 2 [Mo _ 6O _ (19)] Cl _ 218H _ 2O (2)-the first compound containing two different configurations [Mo8O _ (26)] 4- and [Mo6O_ (19)] 2-. Another compound, (C10H10N2) 2 [尾 -MoTi8O26] (3), was obtained by adjusting the pH value of NaOH aqueous solution to about 5.0, and when 110-phenanthroline ligand and transition metal Ni2 were introduced, the pH value was adjusted to about 7.0 with NaOH aqueous solution. Compound 4: [Ni (phen) 2] 2 (尉 -Mo8O _ (26) (4) We have characterized the four compounds and found that they all have low band gap width and are potential wide-band gap semiconductor materials, so we have studied the photodegradation of dyes for these four compounds. It is found that compounds 3 and 4 have a good response to visible light, which proves that they are very effective photocatalysts. Under visible light irradiation, both compounds can degrade organic dye methyl orange and exhibit high photocatalytic degradation ability.
