As a photocatalytic material, nano WO3 is welcomed as it has divergent admirable features like high stability, non-toxicity, ease of preparation, suitable band edge positions and facile generation of active oxygen species in the aqueous medium. Nano WO3 finds unparalleled opportunity in wastewater purification under UV/visible light. While the perennial failings of the photocatalytic material emanate from the stumbling blocks like rapid charge carrier recombination and meager visible light response.

As a new radiation shielding material, tungsten heavy alloy has been widely used in various types of medical equipment such as CT, linear accelerator, PET, and γ camera, to provide better radiation protection and beam guidance.

As a semiconductor photocatalytic material, WO3 nanomaterial can be prepared using amorphous peroxo-tungstic acid for the degradation of various organic compounds. The experts have investigated the photocatalytic activity and physical properties on WO3 photocatalysts prepared by various methods.

Tungsten alloy syringe shield applied for PET is made of high density tungsten alloy and lead glass. After special processing, such a syringe shield has a good radiation shielding effect on short-lived radionuclides such as 18F, 11C, etc, to provide good external radiation protection for nuclear medicine workers. PET is an abbreviation of Positron Emission Computed Tomography in English, a relatively advanced clinical examination imaging technology in the field of nuclear medicine.
