Copper phosphotungstate is a product of reaction between phosphotungstic acid and copper nitrate, used as catalyst for petrochemical oxidative desulfurization, catalytic synthesis of acetyl acetal, tetrahydrofuran.

Tungsten oxide photocatalyst mainly use WO₃ as raw material, it can be applied in air purification, anti-fog and self cleaning, anti-baterial.

Bismuth phosphotungstate is a bismuth salt of phosphotungstic acid, as a catalyst with green powder, chemical formula of BiPW₁₂O₄₀, generated by metathesis and microwave solid-phase synthesis method from phosphotungstic acid and bismuth trichloride.

Nano tungsten trioxide is tungsten trioxide with grain size less than 100nm, it has larger specific surface area and can be produced by solid phase reaction method, it has strong magnetic absorption ability, catalytic property and gas sensitivity.
