Water splitting niobates

The extension of this approach to artificial leaves based on titanates, niobates, tantalates, metal nitrides and phosphides, metal sulfides, and other transition metal oxides appears possible and useful in order to enhance the photocatalytic efficiency. In addition, the construction of multicomponent systems such as Ti02-CdS or MoS2-CdSe for overall water splitting could also lead to further improvements. This... [Pg.116]

While Nb20s is not an active photocatalyst for water splitting, many niobates do split water upon UV irradiation. One of the best studied catalysts, K4Nb60n, was first discovered by the Domen laboratory in 1986.The layered compound consists of NbeOn sheets (Figure 2) held together by K ions. The sheets are composed of edge- and comer-shared NbOe octahedra and the material has a band gap of... [Pg.20]
