Photocatalytic Activity of RuO_2-loaded Pb_xWO_4 (x = 0.2-1.1) for Water Decomposition
In the presence of RuO<SUB>2</SUB>, Pb-deficient lead tungstates, Pb<I><SUB>x</SUB></I>WO<SUB>4</SUB> (<I>x</I> < 1.0), showed higher photocatalytic activity compared to stoichiometric PbWO<SUB>4</SUB> for water decomposition. The highest activity was obtained at <I>x</I> = 0.75 in the range <I>x</I> = 0.2–1.1. The effects of the electronic structures on the photocatalysis are suggested.
