Microwave-assisted synthesis of indium tin oxide nanocrystals in polyol media and transparent, conductive layers thereof

Oxide Nanomaterials: Synthetic Developments, Mechanistic Studies, and Technological Innovations

“…Therefore, various groups have reported microwaveassisted routes to SnO 2 . [122][123][124][125][126][127][128][129][130] One of them demonstrates how the technical potential of MW-ST approaches can be explored through the construction of special microwave ovens that induce higher field strengths within the samples than the commercially available models. [124] As a result, the reaction temperatures are reached very quickly, thereby reducing the reaction times to only 60 seconds.…”

“…To finally obtain phase-pure rutile particles, a minimum HCl concentration of 6 mol/L is required. [206] Nanoparticles of the gas-sensing oxide SnO 2 cannot only be accessed conveniently through MW-HT methods, [122][123][124][125][126][127][128][129][130] but also by the incorporation of a room-temperature ionic liquid, such as [C 16 mim][Br], into a sol-gel process and subsequent heat treatment. [207] Similar to the IL-assisted formation of rutile nanoparticles, [206] this "green chemistry" approach is based on a strong interaction between the IL and tin oxide that is reinforced through hydrogen bonding and the p-p stacking of the imidazolium rings.…”

Influence of pH in Obtaining Indium Tin Oxide Nanoparticles by Microwave Assisted Solvothermal Method

“…Besides, by controlling the synthesis conditions and time of reaction it was possible to decrease the reaction time in four times when compared to other synthesis 25 . Comparing with a hydrothermal method using infrared heating, which needs 12h after calcination in order to crystallize the material 28 , the microwave method is much faster and produces less byproducts.…”

Uranium Oxide Nanocrystals by Microwave‐Assisted Thermal Decomposition: Electronic and Structural Properties

“…The IR spectrum (Figure 4) showed vibrational bands at 3500-3000 cm -1 for ν(O-H), 3000-2800 cm -1 for ν(CH 2 ), 1450-1250 cm -1 for δ(CH 2 ), and 1200-1000 cm -1 for ν(C-O), which is consistent with reported values for DEG. [17] The band at 1750-1650 cm -1 [ν(C=O)] corresponded to carbonyl groups, which can either be ascribed to carbonic acid formed by adsorbed atmospheric CO 2 or to diglycolic acid formed through partially oxidized DEG. There are several publications on CO 2 activation using molecular uranium compounds, in which the metal-mediated redox transformation led to formation of CO and uranium carbonate species with higher oxidized central uranium atoms.…”
