As a photocatalytic material, WO3 has high photocatalytic activity and stability, so it has good industrial application prospects in the field of photocatalysis. You know, ethylene is harmful for storage and fresh-keeping of fruits and vegetables. Photocatalytic technology is an effective and environmentally friendly approach for degrading ethylene. Some experts have synthesized a WO3 photocatalyst using synergetic internal Fe3+ doping and superficial Pt loading for ethylene degradation under visible-light irradiation.

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.

WO3 is a visible-light responsive photocatalyst that absorbs light up to 480 nm with several advantages such as low cost, harmlessness, and stability in acidic and oxidative conditions. WO3-based photocatalysts have various applications such as photodegradation of organics, air purification, self-cleaning, CO2 photoreduction, heavy metal ion treatment, hydrogen evolution from splitting water, and bacterial disinfection.

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.
