Oxygen Yield

Four iron complexes were used as pre-catalysts in BiVO4–NaIO3 photocatalytic water oxidation systems. The best-performing system afforded a rather high oxygen yield and apparent quantum efficiency yield of 99.1% and 44.3%, respectively.

H2 Formation

A novel Zr2ON2 catalyst was successfully prepared by nitriding ZrO2, which has a potential enough for H2 formation by the reduction of water under UV irradiation. It was found that the Zr2ON2 had a stable photocatalytic activity for water oxidation and reduction in the presence of sacrificial reagents (methanol or Ag+) under visible light irradiation (λ < 500 nm).

Light Activity

This TiO2catalyst is modified by two means of doping and dye-sensitization to decompose the water into hydrogen under visible light irradiation in this paper. By exploring the mechanisms of the modification with two ways, it is found that the modification can make TiO2semiconductor with only UV photocatalytic activity become a catalyst with the visible-light activity. The experiments demonstrate that quantum efficiency and energy conversion efficiency of the doped catalyst is respectively 1.5% and 0.5%, and that of the sensitized catalyst is respectively 2.13% and 0.89%. By comparison the doped TiO2catalysts have better prospect in the application because of the instability of the sensitized catalyst.

Synergic Effect

CdS/Ag2S/g-C3N4 ternary composites showed excellent photocatalytic performance toward H2 evolution. Their improved photocatalytic activity could be attributed not only to the synergic effect, but also to the introduction of Ag2S.
