Аннотация
В работе изучены зависимости скорости фотокаталитического выделения водорода под действием видимого излучения от концентрации триэтаноламина и гидроксида натрия для фотокатализатора 0.1 масс. % Pt/g-C3N4. Кинетические зависимости скорости реакции от начальной концентрации субстрата были описаны мономолекулярной моделью Ленгмюра-Хиншельвуда. Найдены оптимальные начальные условия для высокоэффективного протекания процесса выделения водорода. Показано, что в таких условиях катализатор является стабильным материалом в длительных экспериментах. Максимальная скорость образования водорода составила 7,2 ммоль г-1 ч-1.
