Objectives. Catalytically active materials are required in different chemical engineering processes. This makes the development of new materials with high efficiency and original ways in which to obtain them of significant interest. The present work investigates the synthesis of catalytically active material including electrode materials, as well as their improved efficiency due to the nanodecoration of their surface.

Methods

Methods. An aluminum folio was nanoperforated (nanoscalloped) by high-voltage anodization in an acidic medium. The effective electrode material was obtained as a metallic nickel replica rather than an oxide layer of the product. To study the surface state of aluminum obtained in this manner, a scanning electron microscope (Hitachi-SU8200) was used. The elementary composition of the aluminum was determined by back-scattered X-ray irradiation.

Results

Results. The nickel replica obtained in the above-described process exceeded the catalytic activity estimated by methanol oxidation of the unprocessed nickel 70–150 times.

Conclusions

Conclusions. The present paper demonstrates the potential of creating effective catalytically active nanopillar materials using the metallic rather than metal-oxide part of a layer of anodized aluminum as a matrix template. 

Цели

Цели. Каталитически активные материалы остаются востребованными в различных химико-технологических процессах, поэтому актуальными являются исследования, направленные на поиск новых эффективных материалов и оригинальных путей их получения. Настоящая работа посвящена созданию ленточных каталитических, в том числе электродных материалов, эффективность которых увеличена за счет нанорифления поверхности.

Методы

Методы. Методом высоковольтной анодной обработки на поверхности алюминиевой фольги формировалось нанорифление. Эффективный каталитически активный материал получали как никелевую реплику с металлической алюминиевой ленты. Для определения состояния поверхности алюминия использовали сканирующий электронный микроскоп Hitachi-SU8200 (Япония), для элементного анализа состава поверхности – обратную рентгеновскую фотоэлектронную микроскопию.

Результаты

Результаты. Полученный нановорсистый никелевый материал превосходит по каталитической активности гладкий никель при окислении метанола в 70–150 раз.

Выводы

Выводы. Продемонстрирована возможность использования в качестве темплатной матрицы для создания эффективных нановорсистых никелевых ленточных катализаторов, в том числе электродов, не алюминий-оксидной (как предлагалось ранее), а металлической части алюминиевой фольги, подвергнутой высоковольтному анодированию.
