Synthesis of new visible light active photocatalysts of Ba (In1/3Pb1/3M'1/3)O3 (M' = Nb, Ta): A band gap engineering strategy based on electronegativity of a metal component
Article Abstract:
The synthesis of new, efficient, visible light active photocatalysts through the incorporation of highly electronegative non-transition metal Pb or Sn ions into the perovskite lattice of Ba(In1/3M1/3M'1/3)O3 (M = Sn, Pb; M' = Nb, Ta) is discussed. A greater photocatalytic activity was observed in Pb-substituted derivatives under visible and ultraviolet-vis irradiations as compared to ternary Ba(In1/2M'1/2)O3 and quaternary Ba(In1/3Sn1/3M'1/3)O3 compounds (M' = Nb, Ta).

Visible-light-induced photocatalytic degradation of 4-chlorophenol and phenolic compounds in aqueous suspension of pure titania: Demonstrating the existence of a surface-complex-mediated path
Article Abstract:
The visible-light-induced degradation reaction of 4-chlorophenol was investigated in aqueous suspension of pure TiO(sub 2). This study clearly demonstrates that phenolic compounds can be degraded on pure TiO(sub 2) under visible light through the surface complexation mechanism on the basis of reactivity, DRUVS, and photocurrent measurements although the fraction of surface-complexed phenolic compounds in aqueous TiO(sub 2) suspension is very small.

Photocatalytic reactivities of Nafion-coated TiO(sub 2) for the degradation of charged organic compounds under UV or visible light
Article Abstract:
Nafion-coated TiO(sub 2) particles are prepared, and their reactivities for the photocatalytic degradation (PCD) of charged organic substrates are investigated. The effects of Nafion adlayers on the photoinduced electron transfer and PCD kinetics and mechanisms are discussed.
