В статье представлены результаты изменения размеров пор в зависимости от количества порообразующего агента и измерения удельной поверхности в зависимости от температуры спекания. Трехмерный пористый фотоанод производился из смеси наноразмерных порошков Co3O4, и TiO2 с различным количеством ПА (порообразующий агент) для дальнейшего смешивания в водном растворе. Исследования морфологии трехмерного тонкопленочного пористого фотоанода методами СЭМ показало образование пористой структуры с субмикронными размерами пор зависящих от добавляемого ПА. Наибольшая площадь поверхности трехмерной структуры будет достигнута с использованием разработанной технологии, использующей смеси материалов, которые играют роль порообразователей в материале анода, которая позволяет повысить эффективность поглощения света за счет создания смешанной или многослойной структуры из нескольких фотокаталитических материалов.

This paper presents the results of changes in pore sizes depending on the amount of pore-forming agent and temperature of three-dimensional porous photoanodes with a high specific surface area. The largest surface area with a three-dimensional structure will be achieved using the developed technology using a mixture of materials that play the role of pore-forming in the anode material, which makes it possible to increase the efficiency of light absorption by creating a mixed or multilayer structure of several photocatalytic materials.
