Tungsten oxide is used for many purposes in everyday life. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors. Due to its rich yellow color, WO3 is also used as a pigment in ceramics and paints. 2010- AIST reports a quantum yield of 19 % in photocatalytic water splitting with a caesium-enhanced tungsten oxide photocatalyst.
