文摘

Suitable band engineering is important in separating photoinduced electron-hole pairs. Based on the band engineering theory and the quantum size effect, we designed a band-gap-matched photocatalyst. This photocatalyst shows high-efficiency photocatalytic activity (14 mmol h-1) and high-stability.
