В данной работе исследовано влияние селективного фотоосаждения восстановительных и окислительных сокатализаторов (Ag, Ni и Co) на материал ASTO, обеспечивающего эффективное разделение зарядов и направленную активацию CO2. Результаты фотокаталитических испытаний показали, что для образца Ag/ASTO/Co основным продуктом являлся CO с выходом 1.61 мкмоль·г-1·ч-1 и селективностью 63.4%. Введение Ni приводило к увеличению выхода CO более чем в 9 раз (до 15.2 мкмоль·г-1·ч-1) и росту селективности до 79.9%, при этом реакции выделения H2 и образования CH4 оставались подавленными. Полученные результаты демонстрируют выраженный синергетический эффект Ag, Ni и Co и предлагают эффективную стратегию создания селективных фотокатализаторов для восстановления CO2 в водной среде без применения дополнительных реагентов.
