Tungsten trioxide can be applied in hydrogen desulfurization catalyst, SCR denitration catalyst, photocatalyst.

Silver phosphotungstate photocatalyst has excellent catalytic performance, environmental friendliness and other advantages to be widely used, and can be synthesized by microwave solid-phase synthesis and precipitation method.

Tungsten trioxide hydrogen reduction producing tungsten powder uses two steps method which is used for batch production.

Phophotungstic acid application includes catalyst, printing and dyeing, coloring agent, biological sample dyeing, protein precipitation and bipolar ion exchange membrane.
