✦ Synopsis
The physical properties of mixed WO 3 /WS 2 powders prepared by oxidation of WS 2 strongly depend on the temp. and duration of the oxidation. Photocatalytic results for the photodegradation of phenol show that the aqueous suspensions of the mixed WO 3 /WS 2 powders have significantly higher activities than pure WO 3 or WS 2 . The best results are obtained when the surface WS 2 molar fraction is about 0.5. -(DI
