Abstract

Настоящее изобретение раскрывает фотокатализатор, который имеет высокую каталитическую активность, является нетоксичным, имеет длительный срок службы, позволяет использовать видимый свет непосредственно для его фотокаталитической реакции и является особенно применимым для генерирования водорода, и способ его получения. Он содержит соединение кадмия, имеет капсулярную структуру, имеет средний диаметр частиц 100 нм или менее и может быть получен добавлением по каплям раствора соли кадмия в раствор соединения натрия или смешением раствора соединения натрия с суспензией частиц соединения кадмия.Международная заявка была опубликована вместе с отчетом о международном поиске.
