Abstract The reaction of indium(III) nitrate, chloride and sulphate m moltennitrate has been shown by thermogravimetric analysis to be of the Lux-Flood acid-base type, the insoluble product being indium(III) oxide. The temperature of reaction has been shown to increase with coordination of added anionic ligands to the indium (i.e. causing stabilisation), the relative effect being F − > SO 4 2− > Cl

Reaction behavior of bismuth(III) and indium(III) with 2,4,6-tris(2-hydroxy-4-sulfo-1-naphthylazo)-1,3,5-triazine trisodium salt (THT) is established under various conditions. Bismuth(III) forms a 2 : 3 dark red complex (absorption maximum at 530 nm) with the reagent at pH 4–6.5. Indium(III) reacts with THT to form a 1 : 2 dark red complex at pH 3–4.7 (λmax 530 nm) and a 1 : 3 purple blue complex at

MIL-53 represents one of the most notable metal–organic frameworks given its unique structural flexibility and remarkable thermal stability. In this study, a shaker-type ball milling method has been developed into a facile and generalizable synthetic strategy to access a family of MIL-53 type materials under ambient conditions. During the explorations of [M(OH)(fumarate)] (M = Al, Ga, and In), we report

Using ethanolamine (EA), diethanolamine (di-EA) and triethanolamine (tri-EA) as electron donors, the photocatalytic hydrogen evolution and decomposition of the electron donors (pollutants) over Pt/ZnIn2S4 have been investigated. The Pt was deposited on ZnIn2S4 by in situ photoreduction. The three ethanolamines improve notably photocatalytic hydrogen generation with their simultaneous degradation, and their activity order for hydrogen evolution is tri-EA >> di-EA > EA. The adsorption of these donors on ZnIn2S4 was monitored by in situ attenuated total reflection infrared spectroscopy (ATRIR). The order of their adsorption intensity is EA > di-EA >> tri-EA. The activity order depends on their molecular structure and adsorption performance. The effect of concentration of the pollutants on the hydrogen generation rate is consistent with a Langmuir-Hinshelwood kinetic model. The weak basic condition is favorable for the photocatalytic hydrogen generation. A possible reaction mechanism was discussed. (C) 2012 Elsevier B.V. All rights reserved.
