ChEBI · EMBL-EBI ↗ · Källdatum saknas · Källans villkor

A primary alcohol that is dodecane in which a hydrogen from one of the methyl groups is replaced by a hydroxy group. It is registered for use in apple and pear orchards as a Lepidopteran pheromone/sex attractant, used to disrupt the mating behaviour of certain moths whose larvae destroy crops.

In this study, we present a modified polyol method using 1-dodecanol as an additive to synthesize WxVO2 (M). 1-Dodecanol has a boiling point of 259 °C, which is high enough for the polyol method, and can act as both the solvent and capping agent, as shown in inorganic nanoparticle synthesis [20]. Unlike the original polyol method, we found that tungsten could be doped into VO2 (M) with the addition of 1-dodecanol, thereby reducing the MIT temperature of the resulting WxVO2 (M). We investigated the influence of the mixing ratios of EG and 1-dodecanol and the amounts of tungsten precursor on the synthesis of WxVO2. Our results suggest a procedure to dope tungsten into VO2 (M) via the polyol method.

In this study, we carried out the synthesis of tungsten-doped VO2 via a polyol method based on ammonium metavanadate and EG by utilizing WOCl4 and 1-dodecanol as the tungsten source and capping agent, respectively. By conducting extensive characterizations using XRD, DSC, SEM, FT-IR, UV-Vis-NIR spectroscopy, and ICP-AES analysis, it was suggested that WOCl4 coupled with both EG and 1-dodecanol at an optimal ratio was responsible for the successful incorporation of tungsten into W-VEG in the creation of the calcinated compound, WxVO2. Other popular tungsten sources such as WCl6 and Na2WO4 were not effective for the tungsten doping in the polyol process, which indicates the usefulness of our modified polyol method that utilizes 1-dodecanol and WOCl4. However, it should be noted that the incorporation of bulky dodecyl chains into W-VEG seems to result in an increased FWHM value for the melting transition and that the current MIT temperature of WxVO2 at around 51 °C should be further decreased to near room temperature for practical thermochromic applications. In addition, the decrease in the luminous transmittance with the tungsten doping should be improved. These issues suggest that further investigations should be undertaken to find alcohol capping agents less bulky than 1-dodecanol and processes to avoid aggregations.
