DescriptionThe army of titanium dioxide nanotubes.jpg |
Русский: Нанотрубки диоксида титана — перспективный материал для элементов солнечных батарей, элементов энергонезависимой памяти (мемристоров), фотокатализаторов, суперконденсаторов, газовых сенсоров, генераторов водорода. На снимке — массив нанотрубок диоксида титана, синтезированный электрохимическим окислением металлического титана. По-другому этот метод называют анодированием. В результате анодирования в органических электролитах, содержащих фтор, поверхностный слой металла преобразуется в оксидный слой в виде вертикально направленных полых внутри нанотрубок, «запаянных» с одной стороны. Трубки можно изготавливать открытыми с обеих сторон для получения мембран с настраиваемым диаметром пор. Диаметр трубки в образце на фото 70 нм, длина около 1000 нм.
Обработанное электронное изображение нанотрубок получено с помощью сканирующего электронного микроскопа SIGMA VP (Carl Zeiss) в лаборатории синтеза наноматериалов научно-образовательного центра «Наноматериалы и нанотехнологии» Уральского федерального университета. Фотография заняла 3-е место в номинации «Микрофотография» на российском этапе международного фотоконкурса научных фотографий 2017. Работа была опубликована в журнале «Наука и жизнь» №3 2018 на обороте обложки с описанием English: The processed electron image of titanium dioxide nanotubes obtained by anodization of titanium metal. The diameter of tube is 70 nm, the length is 1000 nm. Nanotubular titania is a prospective media for many applications such as solar batteries, memristors, photocatalysis, capacitors, gas sensors, hydrogen generators, etc. |
