Abstract:
Visible-light-induced water splitting was achieved by increasing the visible-light sensitivity of AgTaO3, by the introduction of Nb, generating AgTa1-xNbxO3. After grafting NiO onto AgTa0.7Nb0.3O3, simultaneous, catalytic liberation of H2 and O2 at a molar ratio of ∼2 : 1 was achieved from pure water under only visible-light irradiation.
