A cocatalyst-free Eosin Y-sensitized p-type of Co3O4 quantum dot for highly efficient and stable visible-light-driven water reduction and hydrogen production†
Abstract
Owing to the effect of energy band bending, p-type Co3O4 quantum dots sensitized by Eosin Y showed a high and stable photocatalytic activity (∼13 440 μmol h−1 g−1cat) for water reduction and hydrogen production under visible-light irradiation without any cocatalyst.
