Structural analysis and optical properties of the Bi(2–x)Y(x)WO(6) system

Photocatalytic conversion of solar energy into chemical energy has attracted considerable interest for several decades. One compound already reported as a visible-light-active photocatalyst for water splitting is BiYWO(6), a member of the Bi(2–x)Y(x)WO(6) family of compounds. The structural and opti...

Sumario:Photocatalytic conversion of solar energy into chemical energy has attracted considerable interest for several decades. One compound already reported as a visible-light-active photocatalyst for water splitting is BiYWO(6), a member of the Bi(2–x)Y(x)WO(6) family of compounds. The structural and optical properties of other members of this family have not been reported to date. In this work, we synthesized various compositions of Bi(2–x)Y(x)WO(6), studied their optical properties, and report their structural parameters obtained by utilizing powder diffraction coupled with Rietveld refinement.
