摘要: Photocatalytic decomposition of H2O to form H2 and O2 over NiOK4Nb6O17 powder (1–10 μm, band gap = 3.3 eV), which is an ion-exchangeable layered compound, proceeds steadily more than 50 h under the bandgap irradiation. Maximum activity was obtained when reaction carried out in distilled water where pH ca. 11 by elution K+ quantum efficiency at 330 nm 3.5 ± 0.5% initial stage pretreated NiO(0.1 wt%)K4Nb6O17. Several characteristic features were discussed compared with those NiOSrTiO3.
