| WO3 has been thoroughly investigated and optimized to deliver high single wavelength quantum efficiencies. Unfortunately the stability of this oxide in aqueous environments, aided by an energetically low valence band which is defined largely by O 2p energy levels, also brings a large band gap which renders these materials transparent to most of the incident solar illumination. A series of hydrated Tungsten-Molybdenum oxides have been synthesized by hydrothermal and microwave radiation techniques. In both cases the WO3·0.33H2O crystal lattice can be substituted with up to 75% Mo without structural alterations of the orthorhombic host structure. These products have a band gap suited at the visible range (~2.00 eV). Experimental data were explained by means of first-principle calculations in the framework of DFT and DFT+U; indirect semiconductors were obtained. Both compounds were evaluated for H2 production. | |
