Photocatalytic activity of RuO2-loaded PbxWO4 (x=0.2-1.1) for water decomposition

Kadowaki H, Saito N, Nishiyama H, Shimodaira Y

In the presence of RuO2, Pb-deficient lead tungstates, PbxWO4 (x < 1.0), showed higher photocatalytic activity compared to stoichiometric PbWO4 for water decomposition. The highest activity was obtained at x = 0.75 in the range x = 0.2-1.1. The effects of the electronic structures on the photocatalysis are suggested.
