摘要

A method for producing a tungsten trioxide powder for a photocatalyst according to the present invention is characterized by comprising a sublimation step for obtaining a tungsten trioxide powder by subliming a tungsten metal powder or a tungsten compound powder by using inductively coupled plasma process in an oxygen atmosphere, and a heat treatment step for heat-treating the tungsten trioxide powder obtained in the sublimation step at 300° C. to 1000° C. for 10 minutes to 2 hours in an oxidizing atmosphere. A tungsten trioxide powder which is obtained by the method for producing a tungsten trioxide powder for a photocatalyst according to the present invention has excellent photocatalytic performance under visible light.
